PRETORIA, South Africa (CBS) -- Defense lawyers for Oscar Pistorius are stepping up their fight today to keep the South African sprinter out of prison. They insist the shooting death of his girlfriend was a tragic accident. But police say the runner is a flight risk and should not be granted bail.
Oscar Pistorius covered his head with a blanket as he rode back to court in a police car for day two of his bail hearing in South Africa's capital.
His defense team is trying to keep him out of jail before he goes on trial for the premeditated murder of his girlfriend, model Reeva Steenkamp.
Prosecutors insist the runner is a cold-blooded killer who shot Steenkamp after a heated argument in the early hours of Valentine's Day.
They say a witness heard non-stop shouting coming from Pistorius' home before the shooting.
The Paralympic superstar, known as the Blade Runner for his prosthetic legs, says he was not wearing them the night of the killing.
But a police detective says the bullets were fired down through the top of Pistorius' bathroom door suggesting the athlete was using his artificial legs.
Pistorius said thought he was shooting at a robber when pumped four bullets through the locked door. But when he broke it down with a cricket bat, he realized he had shot Steenkamp in the head, arm and hip.
Prosecutors tell it differently, saying the sprinter took time to put on his artificial legs, walk across the room, and then open fire on Steenkamp who was hiding in the bathroom.
Family and friends buried the super model and law graduate on Tuesday.
Pistorius says he was deeply in love with Steenkamp and was filled with horror and fear as she died his arms.
South African police say they found two containers of testosterone and needles in the Paralympic athlete's bedroom. Defense lawyers say the substance was an herbal remedy, not a banned steroid.
