Los Angeles, California (CNN) -- Dr. Conrad Murray waited at least 21 minutes after he found pop star Michael Jackson unresponsive before calling for an ambulance, a prosecutor said at the start of Murray's preliminary hearing Tuesday.
"By all accounts, Michael Jackson was dead in the bedroom at 100 North Carolwood prior to the paramedics' arrival," said Los Angeles County Deputy District Attorney David Walgren.
Michael Jackson's mother, Katherine, sister La Toya, and brothers Randy and Jackie sat in the second row of the courtroom during Tuesday's opening session.
Los Angeles County Superior Court Judge Michael Pastor will hear testimony over the next two weeks as he decides whether there is probable cause to try Murray on an involuntary manslaughter charge in the pop star's June 25, 2009, death.
The coroner concluded Jackson died from "acute propofol intoxication," in combination with "the contributory effects of the benzodiazepines," Walgren said. CNN
