Oscar Pistorius 'knew what he was doing': Chilling claims as bullets from crime scene revealed

Bullets from the gun Oscar Pistorius used to kill his girlfriend Reeva Steenkamp have been shown for the first time as part of a chilling documentary into her murder.

Pistorius, 30, a double-amputee Paralympic champion sprinter, was found guilty of Ms Steenkamp’s murder in July last year.

He shot her four times while she stood in a bathroom on Valentine’s Day 2013.

For the first time, a ballistics expert has spoken to the Discovery Channel claiming Pistorius “knew what he was doing” and explaining why the bullet fragments were so crucial to the case.

The documentary also revealed more than 600 photos were taken of the crime scene.

Captain Chris Mangena helped form crucial evidence, which overturned Pistorius’ initial conviction for culpable homicide, to murder.

The “Blade Runner” pleaded not guilty in 2014, and argued he thought his model girlfriend was a burglar. Prosecutors claimed the killing was the culmination of a terrible fight between the pair.

But Mr Mangena, in a documentary, Faking It: Tears of a Crime, said the recovered bullet fragments were a vital in proving Pistorius’ guilt.

Using the bullets, the expert was able to determine where Pistorius was standing when he fired each shot.

Mr Mangena claims Ms Steenkamp, 29, ran into the bathroom and closed the door.

“The first shot was on the hip and after this shot, she fell down,” he said.

“Most likely she could have screamed. She could have screamed and fell down.”

Graphics illustrate the trajectory of the bullets, showing Ms Steenkamp would have been in a standing position when the first shot was fired.

In court, Pistorius said he heard the sound of a magazine rack in the bathroom.

The documentary claims this rack was on the other side of the cubicle.

Mr Mangena said Ms Steenkamp fell onto the rack.

He claimed Pistorius heard the sound of the wooden rack and that’s when he changed direction, fired three more shots with one hitting the model in the head.

“He fired towards the position of the magazine rack,” Mr Mangena said.

“So, to me, it shows that he knew what he was doing.”

Pistorius claimed during the trial he had no idea his girlfriend was behind the door and often broke down in tears or prayed when she was mentioned.

In the documentary, body language specialist Cliff Lansley claimed this was a tactic to gain favour with the judge.

Mr Lansley said Pistorius knew he was going to be found guilty and used the emotional display to gain sympathy.

Prosecutors are still hoping to increase Pistorius’ sentence claiming it’s too lenient.
