Prosecutor: Error in declaration of testosterone found at Pistorius’ home

One of the more explosive "revelations" to come from the Oscar Pistorius bail hearings has been discounted by the prosecution.

Medupe Simasiku, the case's prosecutor and a member of South Africa's National Prosecution Agency, indicated that an investigating officer erred when he identified a substance found in Pistorius' home as testosterone.

Detective Warrant Officer Hilton Botha, the investigating officer at the scene, had earlier indicated that he had discovered boxes of needles and testosterone. However, while the needles were indeed discovered, the exact makeup of the substance discovered remains under investigation.

The alteration is significant from a public-relations standpoint, as attorneys for Pistorius claimed that it gave a negative connotation to Pistorius' actions and behaviors. The International Paralympic Committee said shortly after Botha's statement that Pistorius passed two dug tests last year. The International Olympic Committee did not test Pistorius during the London Games.

Pistorius' attorneys said that the substance was neither a steroid nor testosterone, but a legal herbal remedy.

Botha, who has 16 years' experience as a detective and 24 as a deputy, initially characterized the substance he discovered in Pistorius' bedroom as a "steroid," but the prosecution immediately corrected him. Simasiku, the prosecutor, later said that Botha simply read the first few letters of the substance and believed it was testosterone.

Defense attorneys pulled apart many of Botha's claims about the case on cross-examination, strengthening Pistorius' bid to make bail. A trial is not expected for many months. (See a full breakdown of the defense's cross-examination of Botha here.)

Pistorius has been accused of killing his girlfriend, model Reeva Steenkamp, by firing four shots through their bathroom door. Pistorius' attorneys contend he believed he was firing at an intruder.
