In an interview with a South African newspaper, Reggie Perumal, an independent crime scene investigator based in South Africa said that the bathroom door would form a key piece of evidence in the case.
“It is critical that we examine this door so that we can see the trajectory of the bullets and establish exactly where she was in the toilet when she was shot,” Mr Perumal told the Cape Times newspaper.
“Next to the post mortem results, this is the most crucial information needed.”
It was also revealed that Perumal noticed the possibility that a spent bullet might be in the toilet bowl before one was recovered.
Perumal also suggested that substandard crime scene investigation was leading to many miscarriages of justice in South Africa.
During Pistorius’s bail hearing, which gripped the world, the case’s investigating officer Hilton Botha floundered under cross examination.
Botha changed his testimony, suggested testosterone has been found when at the scene, when it wasn’t, and admitted he could find nothing that would contravene Pistorius’s version of events.
Botha was later dropped from the case after attempted murder charges were reinstated against him.
Pistorius was this week reported to be complying with his bail conditions.
Pistorius’s trial on charges of the murder of his model girlfriend Reeva Steenkamp will take place in June
