Oscar Pistorius Case: Dramatic Details Emerge on Eve of Blade Runner's Murder Trial

On Valentine's Day last year, security guards from Pistorius's South African luxury estate called him after the early morning shooting and asked if "everything was in order," according to a court document obtained by South African television station eNCA.
[H]e indicated that he was fine," the document reportedly says, adding, "He never asked for their assistance and did not make a report about the shooting incident to them."
Pistorius, who has claimed the shooting was a case of mistaken identity – he thought he was shooting an intruder and not Steenkamp, 29, – previously said he immediately scrambled for help.
In a sworn affidavit at an earlier bail hearing, Pistorius said, "I phoned Johan Stander, who was involved in the administration of the estate, and asked him to phone the ambulance. I phoned Netcare (a private emergency services company) and asked for help. I went downstairs to open the front door."
The court document, which both sides deny leaking, also says that a female witness heard "talking like fighting," which she assumed was an argument. "This stopped after the shots were fired," the document states.
Pistorius has maintained the couple spent a loving night together.
While the report shows the basic outline of the state's game plan to prove Pistorius is guilty, one revelation could be beneficial to the defense.
The report says the prosecution's own ballistics analysis backs up Pistorius's claim that he was not wearing his prosthetic legs when he fired his gun four times through a locked bathroom door, killing his model girlfriend Steenkamp. The defense has suggested if the shooting were premeditated he would have had on his prosthetics.
The trial begins March 3 in Pretoria, the capital of South Africa. Known as the Blade Runner, Pistorius, the first paralympian to compete in the able-bodied Olympics, is charged with premeditated murder, illegal possession of ammunition, as well as two additional gun-related charges.
