"I'm monitoring him ... and he fell asleep," said Murray. "I sat there, watched him for a long enough period that I felt comfortable .. Then I needed to go to the bathroom. So I got up, went to the bathroom."
"I was gone I would say about two minutes .. Then I came back to his bedside and was stunned in the sense that he wasn't breathing."
Murray said he immediately started cardiopulmonary resuscitation (CPR) and mouth-to-mouth resuscitation.
After continuing those efforts for an unspecified time, he called Jackson's personal assistant, Michael Amir Williams, who was not at the house but who alerted security guards outside to come up to the bedroom.
He said he did not immediately call 911 because he was working intensively on trying to revive Jackson. "To speak to a 911 operator would be to neglect him," he said.
Eventually another security guard arrived and called 911 at 12:20 pm, before starting to help Murray pump Jackson's chest. Paramedics arrived about six minutes later and continued efforts for about half an hour.
With no signs of life, doctors said they were ready to pronounce death at 12:57 pm, but Murray insisted he be taken to the UCLA Medical Centre -- where the star was eventually pronounced dead at 2:26 pm.
