>> reporter: oscar pistorius arriving in court today, inside no hiding from photographers. today the chief police investigator challenged pistorius ' account. he said he would have had to walk 23 feet from the bedroom, go inside the bathroom and fire tour times from five feet away. believing a dangerous intruder was inside. the investigator said pistorius would have been wearing his prosthetic legs, because the bullets were shot high into the door with a downward trajectory. but pistorius stated he was not wearing his prosthetics which is why he said he felt so vulnerable. police also say they have witnesses, a neighbor who said she heard what sounded like fighting for an hour from pistorius ' home and then gunfire. another neighbor says he heard shots, looked outside, saw lights on inside the home, heard a woman scream two or three times and then another few shots. pistorius ' uncle addressed the allegations.

>> they're just not true. this is it. he's not a violent person. he's a peacemaker.

>> reporter: but there are other questions. if pistorius was screaming, yelling to his girlfriend to call police about a burglar, as he claims, wouldn't she have responded from the bathroom? or when he fired the first shot. and police said they found steroids, testosterone and needles for injection in his bedroom. but he said he didn't know what the substance was and saw the label and made an assumption. his lawyer says it's an herbal remedy . it's being tested. last week he was brought to the hospital for tests. tomorrow, a likely ruling on whether the olympic great is released on bond or held in prison. michelle kosinski , nbc news, pretoria, south africa .
