Continuity mistake: When the police investigator is speaking with the reporter after leaving the victim's apartment before getting in his car, just as he says "No undergarments were found in the apartment", the reporter is shown lowering the notepad in his left hand and has his right hand with a pen in it, placed on top of the car. In the next shot, the reporter's left hand and his notepad are suddenly placed on top of the car, writing in the notepad with his pen. The shot after that, only the right hand is placed on top of the car and the left hand is at his side. (00:25:48)

Continuity mistake: When the investigator begins confessing to the other police officers, one of them has him eat a handful of salt.

When he says "But I left fingerprints all over her apartment", a larger amount of salt can be seen on his upper chin that wasn't there a minute earlier. (01:45:52 - 01:46:57)
