Michael Jackson's personal physician, Conrad Murray, has gone on trial in Los Angeles, charged with involuntary manslaughter of the singer.

迈克尔·杰克逊的私人医生，康拉德·默里以过失杀人罪在洛杉矶某法院受审。

The defence says that Dr Murray was Jackson's friend before he became the star's physician
Prosecutors² said he acted with "gross negligence³（重大过失） " and gave Jackson a lethal⁴ dose of the sedative⁵（镇静剂） propofol that caused his death in June 2009.

The defence said Jackson gave himself too much of the drug, a sleeping aid.

Dr Murray, 58, who denies the charge, could face four years in jail and the loss of his medical licence.

Slurred⁶ message

In Tuesday's opening statement, lead prosecutor¹ David Walgren told the court the evidence would show "Conrad Murray repeatedly acted with gross negligence, repeatedly denied appropriate care to his patient, Michael Jackson".

"That misplaced trust... cost Michael Jackson his life."

The jury was shown a photo of the 50-year-old singer's pale body lying on a gurney（轮床） after he died, and heard a recording⁷ of the pop star slurring⁸ while talking about planned comeback concerts.

Mr Walgren said the audio, aired in public for the first time, had come from a message on Dr Murray's mobile phone.

"When people leave my show, I want them to say, 'I've never seen nothing like this in my life'," says Jackson, apparently⁹ heavily drugged, on the audio.

"Go. Go. I've never seen nothing like this. Go. It's amazing. He's the greatest entertainer in the world."

The prosecutor said Jackson's difficulty in speaking on the recording showed that Dr Murray ought to have realised the star should not have taken any more propofol.

Mr Walgren said that after administering what it says was the fatal dose, Dr Murray had not been attentive¹⁰ to Jackson's health.
