Oscar Pistorius Update: Olympian to be indicted on murder charge Monday, prosecutors say; trial set for early 2014

(CBS/AP) JOHANNESBURG - Oscar Pistorius will be indicted for premeditated murder on Monday and the double-amputee Olympian will go on trial in early 2014, about a year after fatally shooting his girlfriend, prosecutors said.

In a somber twist, Pistorius will be indicted on the day the woman he killed, Reeva Steenkamp, would have celebrated her 30th birthday.

National Prosecuting Authority spokesman Medupe Simasiku told The Associated Press on Friday that the exact date for the trial had not yet been set and would likely be decided on Monday, Pistorius' next scheduled appearance in court.

The indictment papers will be served at Pretoria Magistrate's Court and the prosecution will retain a main charge of premeditated murder, Simasiku said. Pistorius faces a life sentence with a minimum of 25 years in prison if convicted on that charge.

Pistorius was initially charged with premeditated murder for Steenkamp's death for bail purposes while police investigated the circumstances of the Valentine's Day shooting. Police said this week they had completed their six-month investigation and are convinced Pistorius "had a charge to answer to," leading to the indictment.

Additional charges are "possible," said Simasiku. He declined to comment on South African media reports on Friday that charges relating to Pistorius allegedly discharging a firearm recklessly in two other incidents would be added to the indictment.

Pistorius denies he committed murder and says he shot Steenkamp by mistake in the early hours of Feb. 14 because he thought she was a nighttime intruder in his bathroom in his villa in a gated community in the South African capital, Pretoria.

Anneliese Burgess, Pistorius' spokeswoman, said the athlete's defense team also wouldn't be commenting on the charge or charges but they expect to see a copy of the indictment and related papers before Monday's court proceedings so they can prepare.

Those papers are also expected to include a witness list and detail some of the evidence police have gathered in the six months since Pistorius fired four bullets from his licensed 9mm gun through a locked toilet cubicle door in his bathroom, hitting his girlfriend three times and killing her.
