Five revelations from Oscar Pistorius murder trial

By Mirror

"Exactly what happened behind that door, we will never know."

These were perhaps the most memorable words from ballistics expert Tom Wolmarans on Day 29 of Oscar Pistorius' murder trial.

The former police officer spent all day on the stand giving evidence.

After disputing several of the state's theories about when and how the bullets hit Reeva, he came under scrutiny from prosecutor Gerrie Nell.

It was a tetchy affair and points were scored by either side.

Here's five things we learned from the evidence:

1. State ballistics evidence 'makes no sense'

Tom Wolmaran rejected the state's theory that the injury found on Reeva's back was caused by a bullet ricocheting off the wall.

He says the bullet rebounded and ended up in the toilet bowl and that the injury could have been caused by her landing on the magazine rack.

Prosecutor Gerrie Nel argued the markings of the injury did resemble the markings of the bullet.

"I can't see the resemblance," said Wolmaran.

2. Reeva was standing close behind the door when she was shot

Wolmarans said Reeva was standing around 20cm from the door when she was shot.

The first two bullets hit Reeva's hip and arm, he said.

She fell backwards to her right and was then hit by a bullet which caused the head wound.

3. The defence tried to do a cricket bat v gunshot test and failed

Wolmarans said he was present when a decibel test was carried out to see if a cricket bat hitting a door and a gunshot could be mistaken.

He said he thought they were "very similar", but then backtracked on the findings by saying "I'm not a sound expert".

He said the door moved because it wasn't "stable" and so the experiment was "a mishap".

He also claimed to suffer from tinnitus - a constant ringing in the ears.

4. 'I didn't tailor my evidence to suit defence case' - Wolmaran

Wolmaran admitted he met with fellow defence expert Roger Dixon for "a few beers" after he gave evidence in court.

But he insists he did not alter his report to suit his version of events.

He said he took "offence" at Gerrie Nel's suggestion he is biased.

5. Wolmaran pretends to be Reeva

During discussions about the sequence of bullet injuries, Wolmaran asked if he could demonstrate himself behind the toilet door.

In a bizarre few moments, he took off his jacket and hid behind the door pretending to be Reeva.

There was nervous laughter from the court when he said to the judge "You can't see me but I'm behind the door".
