The jury in the trial of Michael Jackson’s doctor has begun its second day of deliberations after failing to reach a verdict on Friday.

The panel of five women and seven men in Los Angeles must decide whether or not Dr Conrad Murray, 58, is guilty of involuntary manslaughter.

The accused denies giving the pop superstar a fatal overdose of a powerful sedative, propofol.

If convicted, the cardiologist could spend up to four years in prison.

He could also be banned from practising medicine if found guilty of Jackson’s June 2009 death from an overdose of propofol, given to help the singer battle chronic insomnia.

The jury – made up of one African American, six whites and five Hispanics – deliberated for more than six hours Friday.

During the six-week trial, 49 witnesses and more than 300 pieces of evidence were presented.

In his closing argument last Thursday, the prosecution said Dr Murray had caused the star’s death through negligence, depriving Jackson’s children of their father and the world of a “genius”.

The defence argued that Jackson was a drug addict who caused his own death by giving himself an extra dose of propofol while Dr Murray was out of the room at the star’s rented mansion in Los Angeles.
