Members of Michael Jackson's family have attended the first day of hearings to determine whether the singer's doctor, Conrad Murray, should stand trial.
The physician is charged with involuntary manslaughter in the death of the popstar, something he denies.
On day one, the court heard that Dr Murray waited up to 20 minutes before calling for help and tried to revive Michael in front of his children.
It was also claimed he removed medical evidence before calling the ambulance.
Doctor Murray has admitted giving Michael Jackson the powerful sedative Propofol in the hours before he stopped breathing, but has pleaded not guilty to the charge of involuntary manslaughter.
If convicted he could face up to four years in prison. The hearing is expected to last two weeks and will determine if there is enough evidence against Dr Murray for a full trial.
Michael Jackson died of cardiac arrest on 25 June 2009, just weeks before he was due to start his This Is It 50 date residency at London's O2 Arena.
