Guard: Murray collected vials before calling 911
Williams, who was Jackson's personal assistant, said his interview with detectives had been delayed. He testified that he received an urgent phone call from Murray on the day of Jackson's death but wasn't told to call 911.
He called Muhammad, who then dispatched Alvarez to Jackson's bedroom on the second floor of the singer's rented mansion in the ritzy Holmby Hills neighborhood of Los Angeles.
The room was off-limits to Jackson's staff, and Muhammad paused before racing up the stairs after reaching the mansion just before paramedics arrived.
He described a heart-wrenching scene. By then, he said, Jackson had been removed from his bed and was on the floor, where Murray, sweaty and frantic, was performing CPR.
Alvarez was pacing nervously, Muhammad told the jury. When he saw Jackson up close, he understood why.
"What did you observe about his face," Walgren asked. "That his eyes were open," Muhammad said. "That his mouth was slightly open."
"Did he appear to be dead," Walgren asked.
Also expected to testify on Thursday are Kai Chase, a chef who spoke to Murray briefly on the morning of Jackson's death, and paramedics who also tried to revive the singer. The medics believed Jackson was already dead by the time they arrived, but Murray insisted the performer be taken to a hospital for additional resuscitation efforts.
Prosecutors contend Murray did not tell any of the bodyguards or emergency personnel that he had been giving Jackson propofol and other sedatives to help him sleep.
Chernoff claimed in opening statements that Jackson gave himself the lethal dose.
