Footage scheduled to be aired by Channel 7 Australia Sunday reportedly shows South African paralympian Oscar Pistorius re-enacting the fatal shooting of his girlfriend, model Reeva Steenkamp.

The footage shows Pistorius running without his prostheses, his hand clenched, apparently pretending to hold a gun, according to the Telegraph of the U.K. Several men in suits are also seen in the video.

Pistorius, 27, is on trial for murder in the case surrounding Steenkamp’s death on Valentine’s Day 2013. He has said he thought he was shooting at an intruder holed up in the bathroom of his Pretoria apartment.

There was no word on why the video was shot or why it has not been shown during the trial. The Telegraph said Channel 7 paid for the video.

Pistorius reportedly is suffering from post-traumatic stress as a result of the killing. His attorney also told the court this week his client is a suicide risk, Agence France-Presse reported.

The trial, which began in March and has been broadcast live on cable, has made both Pistorius’ barrister Barry Roux and prosecutor Gerrie Nel household names. South African universities also have reported an increase in the number of applicants to law school, the Telegraph said.
