Prosecution may reveal evidence at Pistorius hearing

(CBS News) JOHANNESBURG -- Olympic runner Oscar Pistorius, now charged with murder, is due back in court Tuesday for a bail hearing. Pistorius is accused of shooting his girlfriend Reeva Steenkamp at his home in South Africa. He is famous for running wearing carbon blades to replace the legs that he lost as a child.

Since Tuesday's hearing is a bail hearing, the prosecution may be required to reveal a bit about the evidence they have, in terms of what happened in the early hours of Valentine's Day morning.

The prosecution wants to go after Pistorius for premeditated murder, while his defense lawyers are desperate to get him out of custody and out on bail. If the defense argues this is not premeditated murder, they will ask the prosecution to show the strength of their evidence.

The magistrate in the case will then decide whether the prosecution has enough evidence to launch the charge of premeditated murder.

The only details police have confirmed so far are that Steenkamp was shot four times, and Pistorius' 9mm pistol was found at the scene.

Steenkamp will be laid to rest Tuesday in a memorial service in Port Elizabeth, a town on the east coast of South Africa where she grew up.

Steenkamp's family is expected to address the media after the private service. The family has held its silence so far, issuing only written statements. Her father has said he felt no hatred, only sadness; Steenkamp's mother said she can't believe that in a blink, in a breath, her beautiful daughter is gone.
