NASA's Mars Rover Makes Successful First Drill

For the first time ever, people have drilled into a rock on Mars, collecting the powdered remains from the hole for analysis.

Images sent back from NASA's Mars rover Curiosity on Wednesday confirmed that the precious sample is being held by the rover's scoop, and will soon be delivered to two miniature chemical labs to undergo an unprecedented analysis. (Related: "Mars Rover Curiosity Completes First Full Drill.")

To the delight of the scientists, the rock powder has come up gray and not the ubiquitous red of the dust that covers the planet. The gray rock, they believe, holds a lot of potential to glean information about conditions on an early Mars. (See more Mars pictures.)

"We're drilling into rock that's a time capsule, rocks that are potentially ancient," said sampling-system scientist Joel Hurowitz during a teleconference from NASA's Jet Propulsion Laboratory in California.

A Place to Drill

The site features flat bedrock, often segmented into squares, with soil between the sections and many round gray nodules and white mineral veins.

Hurowitz said that the team did not attempt to drill into the minerals or the gray balls, but the nodules are so common that they likely hit some as they drilled down 2.5 inches (6.3 centimeters).

In keeping with the hypothesis that the area was once under water, Hurowitz said the sample "has the potential of telling us about multiple interactions of water and rock."

The drill, located at the end of a seven-foot (two-meter) arm, requires precision maneuvering in its placement and movement, and so its successful initial use was an exciting and welcome relief. The rover has been on Mars since August, and it took six months to find the right spot for that first drill. (Watch video of the Mars rover Curiosity.)

The flat drilling area is in the lower section of Yellowknife Bay, which Curiosity has been exploring for more than a month. What was previously identified by Curiosity scientists as the dry bed of a once-flowing river or stream appears to fan out into the Yellowknife area.

The bedrock of the site—named after deceased Curiosity deputy project manager John Klein—is believed to be siltstone or mudstone. Scientists said the veins of white minerals are probably calcium sulfate or gypsum, but the grey nodules remain something of a mystery.

Triumph

To the team that designed and operates the drill, the results were a triumph, as great as the much-heralded landing of Curiosity on the red planet. With more than a hundred maneuvers in its repertoire, the drill is unique in its capabilities and complexities. (Watch video of Curiosity's "Seven Minutes of Terror.")

Sample system chief engineer Louise Jandura, who has worked on the drill for eight years, said the Curosity team had made eight different drills before settling on the one now on the rover. The team tested each drill by boring 1,200 holes on 20 types of rock on Earth.

She called the successful drilling "historic" because it gives scientists unprecedented access to material that has not been exposed to the intense weathering and radiation processes that affect the Martian surface.

Mini-laboratories

The gray powder will be routed to the two most sophisticated instruments on Curiosity—the Sample Analysis at Mars (SAM) and Chemistry and Mineralogy (CheMin).

SAM, the largest and most complex instrument onboard, operates with two ovens that can heat the sample up to 1,800°F (982°C), turning the elements and compounds in the rock into gases that can then be identified. SAM can also determine whether any carbon-based organic material is present.

Organics are the chemical building blocks of life on Earth. They are known to regularly land on Mars via meteorites and finer material that rains down on all planets.

But researchers suspect the intense radiation on the Martian surface destroys any organics on the surface. Scientists hope that organics within Martian rocks are protected from that radiation.

CheMin shoots an X-ray beam at its sample and can analyze the mineral content of the rock. Minerals provide a durable record of environmental conditions over the eons, including information about possible ingredients and energy sources for life.

Both SAM and CheMin received samples of sandy soil scooped from the nearby Rocknest outcrop in October. SAM identified organic material, but scientists are still trying to determine whether any of it is Martian or the byproduct of organics inadvertently brought to Mars by the rover. (See "Mars Rover Detects Simple Organic Compounds.")

In the next few days, CheMin will be the first to receive samples of the powdered rock, and then SAM. Given the complexity of the analysis, and the track record seen with other samples, it will likely be weeks before results are announced.

The process of drilling and collecting the results was delayed by several glitches that required study and work-arounds. One involved drill software and the other involved a test-bed problem with a sieve that is part of the process of delivering samples to the instruments.

Lead systems engineer Daniel Limonadi said that while there was no indication the sieve on Mars was malfunctioning, they had become more conservative in its use because of the test bed results. (Related: "A 2020 Rover Return to Mars?")

3 Dead in Rolling Gun Battle on Vegas Strip

A drive-by shooting on the Las Vegas strip early this morning by the occupants of a Range Rover SUV, who shot at the occupants of a Maserati, caused a multi-car accident and car explosion that left three dead.

Police said that they believe a group of men riding in a black Range Rover Sport SUV pulled up alongside a Maserati around 4:20 a.m. today and fired shots into the car, striking the driver and passenger, according to Officer Jose Hernandez of the Las Vegas Metropolitan police department.

The Maserati then swerved through an intersection, hitting at least four other cars. One car that was struck, a taxi with a driver and passenger in it, caught on fire and burst into flames, trapping both occupants, Hernandez said.

The SUV then fled the scene, according to cops.

The driver of the Maserati died from his gunshot wounds at University Medical Center shortly after the shooting, according to Sgt. John Sheahan.

The driver and passenger of the taxi both died in the car fire.

At least three individuals, including the passenger of the Maserati, were injured during the shooting and car crashes and are being treated at UMC hospital.

Police are scouring surveillance video from the area, including from the strip's major casinos, to try and identify the Range Rover and its occupants, according to police.

They do not yet know why the Range Rovers' occupants fired shots at the Maserati or whether the cars had local plates or were from out of state.

No bystanders were hit by gunfire, Hernandez said.

"We're currently looking for a black Range Rover Sport, with large black rims and some sort of dealership advertising or advertisement plates," Hernandez said. "This is an armed and dangerous vehicle."

The Las Vegas Convention and Visitors Authority had no immediate comment about the safety of tourists in the wake of the shooting today.

Gbagbo lawyer slams "political trial" at ICC

THE HAGUE: Laurent Gbagbo's lawyer hit out at a "political trial" at the International Criminal Court on Wednesday, where judges are to decide if the Ivorian ex-president should face charges of crimes against humanity.

Gbagbo, 67, is the first former head of state brought before the ICC, where he is accused of masterminding a campaign of violence during a bloody 2010-2011 presidential election standoff in the West African nation in which over 3,000 people died.

"The Ivorian people deserve better than a political trial, they deserve a trial of those who are really responsible for the country's decade-long destruction and the court deserves to have been able to look at what really happened in Ivory Coast," lawyer Emmanuel Altit told the court on the second day of the confirmation of charges hearing.

Gbagbo maintains that he is the rightful president of Ivory Coast and that he was evicted in favour of his rival, current President Alassane Ouattara, thanks to a plot led by former colonial ruler France.

Gbagbo faces four counts of crimes against humanity for allegedly fomenting the wave of violence. He has denied the charges against him.

Altit said the evidence against Gbagbo had holes in it and did not represent reality.

"Why aren't they here, why aren't they being prosecuted?" said Altit, listing officials in Ouattara's government.

While thousands died during the five-month standoff, forces loyal to Gbagbo as well as those loyal to Ouattara have been accused of massive human rights abuses.

Prosecutors and the defence are to spend just over a week arguing their cases before a three-judge bench, who will then decide if there are "substantial grounds to believe that Gbagbo committed the crimes" and should be charged.

The prosecution says Gbagbo masterminded a plan to "stay in power by all means... through carefully planned, sustained and deadly attacks" against Ouattara supporters.

Between November 28, 2010 and May 8, 2011 Gbagbo's forces killed between 706 and 1,059 people and raped more than 35 women, prosecutors say.

His supporters have accused Ouattara's camp of practising "victor's justice" as many of the former president's backers are now behind bars -- including Gbagbo's wife Simone, who is also wanted by the ICC -- while none of those close to the Ouattara regime have been arrested.

The hearings started on Tuesday and are to last over a week, with Gbagbo expected to speak on the final day, February 28.

Railways needs high speed freight corridor to compete with road transport: IFTRT

CHENNAI: The Railways need to introduce mass level exclusive parcel goods trains across the country to provide fast, safe, time bound service, said a latest report by the Indian Foundation of Transport Research & Training (IFTRT).
The Railways should set up retail cargo booking and delivery outlets in collaboration with private entrepreneurs in commercial centres, markets and industrial areas in an effort to effectively compete with road transport.

"Parcel cargo booked through retail outlets and booking points should be linked to internet portal for location of cargo and its delivery to the consignors / consignees," said S P Singh, senior fellow and coordinator, IFTRT. "This will help trade and commerce to source railway parcel services at economical rates and pose direct competition to the powerful segment of goods parcel booking agents, and break their collective pricing behaviour, which is exploiting the consumers," he added. A expanding Railway with high speed freight corridors is key solution to rationalize logistic cost in India, the report said.

The Railways used to command nearly 80% freight share in 1952-52 while road transport comprised a meager 21%. In the ensuing half a century and more, it has slowly relinquished its preeminent position thus increasing India's logistic costs significantly. Currently road freight has 80% share as against rail having only 20% share. "Besides the retail parcel cargo share for road is over 95% and rail has almost 5% share," said the report.

There could be number of reasons for this reversal, but the gradual weakening of rail freight due to negligible investment on replacement and expansion of rolling stock, despite economies of scale and lower freight charges, has led to the rapid expansion of road freight/ truck transport. "The railways slackness has left the entire turf at the mercy of powerful unregulated mass of goods transport agents / transport contractors / common carriers, who on the one hand control and dictate the 85% of freight market by dictating terms with the consignors / traders and on the other hand have strong grip over the 5.6 million truck operators," said Singh.

There is a well knit network of 2.5 lakh good transport agents and common carriers in the country having almost Rs 4,00,000 crore annual turn over, which includes 1,40,000 crore of retail parcel / part load cargo. These common carriers have pricing power to dictate truck rentals and hiring charges across cities and towns. In contrast, almost 90% of truck operators own 1-5 vehicles only which offers them little elbow room or muscle, said Singh.

Florida Python Hunt Captures 68 Invasive Snakes

It's a wrap—the 2013 Python Challenge has nabbed 68 invasive Burmese pythons in Florida, organizers say. And experts are surprised so many of the elusive giants were caught.

Nearly 1,600 people from 38 states—most of them inexperienced hunters—registered for the chance to track down one of the animals, many of which descend from snakes that either escaped or were dumped into the wild.

Since being introduced, these Asian behemoths have flourished in Florida's swamps while also squeezing out local populations of the state's native mammals, especially in the Everglades. (See Everglades pictures.)

To highlight the python problem, the Florida Fish and Wildlife Conservation Commission and its partners launched the 2013 Python Challenge, which encouraged registered participants to catch as many pythons as they could between January 12 and February 10 in state wildlife-management areas within the Everglades.

The commission gave cash prizes to those who harvested the most and longest pythons.

Frank Mazzotti, a wildlife ecologist at the University of Florida and scientific leader for the challenge, said before the hunt that he would consider a harvest of 70 animals a success—and 68 is close enough to say the event met its goals.

It's unknown just how many Burmese pythons live in Florida, but catching 68 snakes is an "exceptional" number, added Kenneth Krysko, senior herpetologist at the Florida Museum of Natural History in Gainesville.

Snakes in the Grass

Finding 68 snakes is impressive, experts say, since it's so hard to find pythons. For one, it's been unusually warm lately in Florida, which means the reptiles—which normally sun themselves to regulate their body temperature—are staying in the brush, making them harder to detect, Krysko said.

On top of that, Burmese pythons are notoriously hard to locate, experts say.

The animals are so well camouflaged that people can stand right next to one and not notice it. "It's rare that you get to see them stretched out—most of the time they're blending in," said Cheryl Millett, a biologist at the Nature Conservancy, a Python Challenge partner.

What's more, the reptiles are ambush hunters, which means they spend much of their time lying in wait in dense vegetation, not moving, she said.

That's why Millett gave the hunters some tips, such as looking along the water's edge, where the snakes like to hang out, and also simply listening for "something big moving through the vegetation."

Even so, catching 68 snakes is "actually is a little more than I expected," said Millett.

No Walk in the Park

Ruben Ramirez, founder of the company Florida Python Hunters, won two prizes in the competition: First place for the most snakes captured—18—and second place for the largest python, which he said was close to 11 feet (3.4 meters) long. The biggest Burmese python caught in Florida, nabbed in 2012, measured 17.7 feet (5.4 meters).

"They're there, but they're not as easy to find as people think," said Ramirez. "You're not going to be stumbling over pythons in Miami." (Related blog post: "What It's Like to Be a Florida Python Hunter.")

All participants, some of whom had never hunted a python before, were trained to identify the difference between a Burmese python and Florida's native snakes, said Millett. No native snakes were accidentally killed, she said.

Hunters were also told to kill the snakes by either putting a bolt or a bullet through their heads, or decapitating them-all humane methods that result "in immediate loss of consciousness and destruction of the brain," according to the Python Challenge website.

Ramirez added that some of the first-time or amateur hunters had different expectations. "I think they were expecting to walk down a canal and see a 10-foot [3-meter], 15-foot [4.5-meter] Burmese python. They thought it'd be a walk in the park."

Stopping the Spread

Completely removing these snakes from the wild isn't easy, and some scientists see the Python Challenge as helping to achieve part of that goal. (Read an opposing view on the Python Challenge: "Opinion: Florida's Great Snake Hunt Is a Cheap Stunt.")

"You're talking about 68 more animals removed from the population that shouldn't be there—that's 68 more mouths that aren't being fed," said the Florida museum's Krysko. (Read about giant Burmese python meals that went bust.)

"I support any kind of event or program that not only informs the general public about introduced species, but also gets the public involved in removing these nonnative animals that don't belong there."

The Nature Conservancy's Millett said the challenge had two positive outcomes: boosting knowledge for both science and the public.

People who didn't want to hunt or touch the snakes could still help, she said, by reporting sightings of exotic species to 888-IVE-GOT-1, through free IveGot1 apps, or www.ivegot1.org.

Millett runs a public-private Nature Conservancy partnership called Python Patrol that the Florida wildlife commission will take on in the fall. The program focuses not only on eradicating invasive pythons but on preventing the snake from moving to ecologically sensitive areas, such as Key West.

Necropsies on the captured snakes will reveal what pythons are eating, and location data from the hunters will help scientists figure out where the snakes are living—valuable data for researchers working to stop their spread.

"This is the most [number of] pythons that have been caught in this short of a period of time in such an extensive area," said the University of Florida's Mazzotti.

"It's an unprecedented sample, and we're going to get a lot of information out of that."

Fiery Debate Over Pistorius' Story at Bail Hearing

As prosecutors today outlined their case against South African Olympian Oscar Pistorius, providing details that they say indicates a premeditated act of murder against his girlfriend, his lawyers swatted at each bit of evidence on the dramatic second day of a bail hearing that will likely foreshadow the upcoming trial.

The Johannesburg courtroom sat riveted as police investigators said that Pistorius, a double-amputee who gained global acclaim for racing at the 2012 London Olympics, shot his girlfriend through a closed bathroom door at a high angle from which he had to be wearing his prosthetic legs.

Prosecutors insisted that Pistorius took a moment to put the legs on, indicating that he thought out and planned to kill Reeva Steenkamp, his model girlfriend, when he shot her three times through a closed bathroom door early on the morning of Valentine's Day.

There was a "deliberate aiming of shots at the toilet from about 1.5 meters [about 5 feet]," prosecutor Gerrie Nel said.

Read Oscar Pistorius' Full Statement to the Court

Nel said Pistorius fired four shots into the bathroom, hitting Steenkamp three times in the head, elbow, and hip.

Nel also said a witness would testify to hearing "non-stop talking, like shouting" in the early hours before the dawn shooting.

'Blade Runner' Appears in Court to Hear Murder Charges Watch Video

Pistorius' lawyer, who argued Tuesday that the runner accidently fired on Steenkamp believing she was an intruder, assailed each bit of the prosecution's evidence, even getting a lead investigator to concede that police had not found anything to conclusively disprove the Olympian's story.

"[The angle] seems to me down. Fired down," Police officer Hilton Botha told the court, suggesting Pistorius was standing high up on his fake legs.

PHOTOS: Paralympics Champion Charged in Killing

But when pushed by defense lawyer Barry Roux, Botha admitted he did not know whether Pistorius was wearing the prosthetics.

When asked about the witness who allegedly heard yelling between Pistorius and Steenkamp, Botha admitted under cross-examination that the woman was about 600 yards -- six football fields -- away at the time.

When the prosecutor questioned Botha a second time, he backtracked to say the witness was actually much closer.

The prosecution showed a floor-plan of the couple's apartment and said there was no way for Pistorius to cross from one side of the bedroom toward the bathroom, or retrieve his hidden pistol, without realizing Steenkamp was not in bed.

"There's no other way of getting there," prosecutor Nel said.

The defense further suggested that Steenkamp had gone to the bathroom on her own, and not to flee from Pistorius, because her bladder was empty. Had she simply run there to hide at 3 am, it would have more likely been full, Roux said.

Asked by defense attorney Roux whether Steenkamp's body showed "any pattern of defensive wounds," suggesting she had put up a fight, Botha admitted it did not.

Prosecutors also said that they found two boxes of testosterone and needles in the bedroom, although the defense disputed the finding, calling the substance a "herbal remedy," not banned drugs or steroids.

Botha told the court today that he arrived at Pistorius' home at 4:15 a.m., Feb. 14, to find Steenkamp already dead, dressed in a white shorts and a black vest, and covered in towels. The first thing Pistorius told police was that "he thought it was a burglar," officials said.

Yemen military aircraft crashes in Sanaa, kills 12

SANAA: A Yemeni military aircraft ploughed into a building in a residential neighbourhood of Sanaa on Tuesday, killing the pilot and at least 11 civilians, medics and witnesses said.

Medics said the toll, which included two children and three women and left another 22 injured, was expected to rise

Several hours after the crash rescue teams were still sifting through the rubble in search of any survivors in the Qadissiya area of homes and shops near Change Square, epicentre of the 2011 uprising that ousted president Ali Abdullah Saleh.

A military source identified the plane as a Russian-made Sukhoi SU-22 attack aircraft, but was unable to say what caused the crash that he said killed pilot Mohammed Shaker.

The defence ministry said the pilot was returning to his base after a training mission and had asked authorisation to land when suddenly the aircraft lost altitude and crashed. An investigation is underway.

"I saw the plane drop and we were afraid it would crash on Sanaa University, but the pilot crashed on nearby buildings," said Mohammed al-Sabri.

The aircraft hit one building on Rabat Avenue in eastern Sanaa, then smashed into another before finally crashing on top of a third, witnesses said.

An AFP correspondent said the building was badly damaged and that several ambulances rushed to the scene as helicopters hovered overhead.

A loud explosion shook the area when the crash occurred, witnesses said. Thick black smoke billowed over the district, where several cars were ablaze.

Panicked residents took to the streets, many screaming.

"We heard a loud explosion and we thought it was a mortar shell that landed on the neighbourhood," one of the residents, Taha al-Inad, told AFP.

An air base is located near the Sanaa international airport, just 15 kilometres (nine miles) north of the capital.

Tuesday's crash was the latest in a series of air accidents in the impoverished Arabian Peninsula country.

In November, a Yemeni air force Antonov M26 crashed during a training mission in a northern district of Sanaa, killing all 10 on board.

A fighter jet crashed on takeoff on a routine training mission in the south in October, killing the pilot and injuring another crew member, after what the defence ministry described as a "technical failure."

And in October 2011, four people were killed when an Antonov crashed on landing at Al-Anad air base in southern Yemen.

Sanaa was gripped by violent clashes between rival military groups during the 2011 uprising to oust Saleh, who finally stepped down a year ago under a UN-backed power transition agreement brokered by the Gulf Cooperation Council.

Tamil Nadu parties slam 'brutal killing' of Prabhakaran's son; Lanka says video 'half-truth'

CHENNAI: Leaders of various political parties in Tamil Nadu strongly condemned the alleged cold-blooded killing of the 12-year-old son of slain LTTE chief V Prabhakaran, purportedly featured by UK-based Channel 4, and demanded action against the Sri Lankan government.

MDMK leader Vaiko demanded an international inquiry into the killing of ethnic Tamils in Sri Lanka and said the forthcoming UN Human Rights Council meeting at Geneva should take a decision on it.

The Sri Lankan army has dismissed as "lies, half-truths, rumours and numerous forms of speculation" the pictures featured in the Channel 4 documentary.

Vaiko wondered why conscience of the people was not stirred even after witnessing "brutal killings" of ethnic Tamils by the Sri Lankan army.

PMK founder Ramadoss described the killing of Balachandran Prabakharan as "total brutality" by the Lankan army. Though there were several evidences of war crimes, countries like India did not act against Sri Lanka and gave a "red-carpet welcome" to its President Mahinda Rajapakse, he said.

"After the present evidence (released by Channel 4), the Indian government should take political and economic steps against the Sri Lankan government," Ramadoss said.

CPM state unit leader G Ramakrishnan and CPI leader D Pandian condemned the killing, saying the Lankan government is not ready for a probe in such matters.

"The Indian government should strongly approach the Sri Lankan government on this matter," CPM said in a statement.

Confirmed: Dogs Sneak Food When People Aren't Looking

Many dog owners will swear their pups are up to something when out of view of watchful eyes. Shoes go missing, couches have mysterious teeth marks, and food disappears. They seem to disregard the word "no."

Now, a new study suggests dogs might understand people even better than we thought. (Related: "Animal Minds.")

The research shows that domestic dogs, when told not to snatch a piece of food, are more likely to disobey the command in a dark room than in a lit room.

This suggests that man's best friend is capable of understanding a human's point of view, said study leader Juliane Kaminski, a psychologist at the U.K.'s University of Portmouth.

"The one thing we can say is that dogs really have specialized skills in reading human communication," she said. "This is special in dogs." (Read "How to Build a Dog.")

Sneaky Canines

Kaminski and colleagues recruited 84 dogs, all of which were more than a year old, motivated by food, and comfortable with both strangers and dark rooms.

The team then set up experiments in which a person commanded a dog not to take a piece of food on the floor and repeated the commands in a room with different lighting scenarios ranging from fully lit to fully dark.

They found that the dogs were four times as likely to steal the food—and steal it more quickly—when the room was dark. (Take our dog quiz.)

"We were thinking what affected the dog was whether they saw the human, but seeing the human or not didn't affect the behavior," said Kaminski, whose study was published recently in the journal Animal Cognition.

Instead, she said, the dog's behavior depended on whether the food was in the light or not, suggesting that the dog made its decision based on whether the human could see them approaching the food.

"In a general sense, [Kaminski] and other researchers are interested in whether the dog has a theory of mind," said Alexandra Horowitz, head of the Dog Cognition Lab at Barnard University, who was not involved in the new study.

Something that all normal adult humans have, theory of mind is "an understanding that others have different perspective, knowledge, feelings than we do," said Horowitz, also the author of Inside of a Dog.

Smarter Than We Think

While research has previously been focused on our closer relatives—chimpanzees and bonobos—interest in dog cognition is increasing, thanks in part to owners wanting to know what their dogs are thinking. (Pictures: How smart are these animals?)

"The study of dog cognition suddenly began about 15 years ago," Horowitz said.

Part of the reason for that, said Brian Hare, director of the Duke Canine Cognition Lab and author of The Genius of Dogs, is that "science thought dogs were unremarkable."

But "dogs have a genius—years ago we didn't know what that was," said Hare, who was not involved in the new research. (See pictures of the the evolution of dogs, from wolf to woof.)

Many of the new dog studies are variations on research done with chimpanzees, bonobos, and even young children. Animal-cognition researchers are looking into dogs' ability to imitate, solve problems, or navigate social environments.

So just how much does your dog understand? It's much more than you—and science—probably thought.

Selectively bred as companions for thousands of years, dogs are especially attuned to human emotions—and, study leader Kaminski said, are better at reading human cues than even our closest mammalian relatives.

"There has been a physiological change in dogs because of domestication," Duke's Hare added. "Dogs want to bond with us in ways other species don't." (Related: "Dogs' Brains Reorganized by Breeding.")

While research reveals more and more insight into the minds of our furry best friends, Kaminski said, "We still don't know just how smart they are."

Oscar Pistorius Describes 'Sense of Terror'

Olympian Oscar Pistorius today denied that he willfully killed his girlfriend, telling a South African court that he shot the woman through his bathroom door because he believed she was an intruder.

Pistorius, 26 and a double-amputee Olympian, was charged today with premeditated murder, or a Schedule 6 offense, which under South African law limits his chances for parole if convicted.

"I fail to understand how I could be charged with murder, let alone premeditated murder because I had no intention to kill my girlfriend," Pistorius said in a statement, read by his lawyer.

"I deny the accusation," he said. "Nothing can be further from the truth that I planned the murder of my girlfriend."

The court adjourned today with no decision on his bail and the hearing is scheduled to resume Wednesday.

PHOTOS: Paralympic Champion Charged in Killing

Pistorius, who gained worldwide fame for running on carbon-fiber blades and competing against able-bodied runners at the Olympics, is accused of shooting his girlfriend, Reeva Steenkamp, at his gated home in Pretoria, South Africa, Feb. 14.

In a statement read by his lawyer today, the runner said he and Steenkamp went to bed together before he was awoken by a noise he thought was an intruder coming from the bathroom.

Filled with a "sense of terror," he removed the 9-mm pistol he kept hidden under his bed and, without putting on his prosthetic legs, began shooting through the bathroom door, according to his statement.

"I was scared and didn't switch on the light," he said. "I got my gun and moved towards the bathroom. I screamed at the intruder because I did not have my legs on. I felt vulnerable. I fired shots through the bathroom door and told Reeva to call police.

"I walked back to the bed and realized Reeva was not in bed. It's then it dawned on me it could be her in there," he said.

That's when he realized Steenkamp was not in bed, he said in the statement. Fearing she was inside the bathroom, he says, he broke down the door using a cricket bat and carried the woman outside, where he called for help, and she soon died.

Excerpts of Prosecutor's Case Against Pistorius

Pistorius appeared in court today for the first time since his Valentine's Day arrest, as prosecutors laid out their case, insisting that the runner could not have mistaken his girlfriend for an intruder.

"[Pistorius] shot and killed an innocent woman," Gerrie Nel, the senior state prosecutor, said in court, adding that there is "no possible explanation to support" the notion that Pistorius thought Steenkamp was an intruder.

Prosecutors said, "There is no possible explanation to support his report that he thought that it was a burglar. Even [in] his own version, he readied himself, walked to the bathroom with the clear intention and plan to kill the 'burglar' and did so whilst the burglar was harmless and contained in a toilet. This in itself also constitutes premeditated murder of a 'defenseless burglar.''

Pistorius said he and Steenkamp were in his bedroom the night before Valentine's Day, when she
was doing yoga exercises and he was in bed watching television. "My prosthetic legs were off," according to his statement. "We were deeply in love and I could not be happier. I
know she felt the same way. She had given me a present for Valentine's Day
but asked me only to open it the next day.

"After Reeva finished her yoga exercises she got into bed and we both fell
asleep."

Later, police responding to neighbors' calls about shouting and gunshots at Pistorius' home in the guarded and gated complex in the South African capital discovered Steenkamp's body. A 9-mm pistol was recovered at the home.

Prosecutors said Steenkamp had arrived at the house with the expectation of spending the night with Pistorius. They said that Steenkamp was shot while in the bathroom, which is about 21 feet from the main bedroom, and that the two rooms are linked by a passage. The door to the toilet was broken down from the outside, prosecutors said, implying that the bathroom door had been locked.

Prosecutors believe it's a case of premeditated murder because, they say, Pistorius had to stop, put on his prosthetic legs, grab a gun and then walk 21 feet to a bathroom.

The premeditated murder charge means that he would likely be sentenced to life in prison if convicted, and that he is likely to be denied bail.
