Details emerge in Pistorious murder case - WNCT | 9 On Your Side Greenville NC & Eastern NC News

Lawyers for Olympian Oscar Pistorius will seek bail for the runner on Tuesday.

The double-amputee has been in jail since Thursday, charged with murdering his girlfriend, model Reeva Steenkamp. Her mother was quoted in a South African newspaper asking, "Why my little girl… Why did he do this?"

But Pistorius' father says it was a tragic accident, that his son acted on instinct because he thought a burglar was in the house.

Investigators have pieced together a different scenario.

CBS News has learned police believe Reeva Steenkamp slept next to Pistorius that night, in his bed, she was still in her nightgown, that she was shot once in the bedroom, then tried to hide in the bathroom, and three more shots were fired through the door, hitting her as she covered her head with her hands.

The shooting has unleashed a barrage of unconfirmed tabloid headlines, including one that police found a bloody cricket bat at the crime scene.

South African journalist Mandy Winer says the bat is a key part of the investigation

Pistorius was the first amputee sprinter to compete at the Olympics, now his legendary career is on hold.

Pistorius has cancelled all future track meets.
