The manslaughter trial of Michael Jackson's personal physician has heard a recording of the late pop star slurring while talking about planned comeback concerts.
Conrad Murray is accused of giving Jackson a lethal dose of the sedative propofol on the night he died in June 2009, the BBC reports.
Dr Murray, 58, denies a charge of involuntary manslaughter at the trial in Los Angeles. He could face four years in jail and the loss of his medical licence.
Lead prosecutor David Walgren said the audio of Jackson slurring his words came from the doctor's mobile phone.
He said the star's difficulty in speaking showed that Dr Murray ought to have realised the star should not have taken any more propofol.
Mr Walgren said that after administering the dose of the drug on the date of Jackson's death, Dr Murray then left to go to the bathroom, and checked his mobile phone. He said the doctor "abandoned (Jackson) to fend for himself."
The prosecutor said when Dr Murray found Jackson unconscious, he did not immediately call the emergency services, instead telling a bodyguard to do so 20 minutes later.
Defence lawyer Ed Chernoff said it was drugs taken by Jackson, without his doctor's knowledge, which had proved fatal.
He told the court the singer had swallowed several pills of the sedative lorazepam on the morning of his death - enough to put six people to sleep.
