Michael Jackson’s doctor could either be cleared of the star’s manslaughter or found guilty over the same piece of evidence.

Both the prosecution and the defence have submitted a voicemail left by Dr Conrad Murray – the last person to see Michael alive – on the day of the late Thriller singer’s death on June 25 last year.

The defence will argue that the call, according to police reports left at 11.54am, shows Conrad wasn’t in a frantic state trying to administer emergency life saving rescusitation to Michael – who died from an overdose of anaesthetic Propofol - at the time.

The prosecution will, however, say the call was made as Michael lay unconscious or already dead at his rented Hollywood home, and Conrad was either not in the room when Jackson passed away or not paying attention to his patient’s needs.
