Michael Jackson’s personal assistant took the witness stand on the second day of Conrad Murray’s involuntary manslaughter trial in Los Angeles.

Michael Amir Williams testified that Jackson’s former doctor called him frantically on the morning of June 25, 2009 begging him to send help for Jackson, who lay dying in the bedroom of a rented Holmby Hill mansion.

“He said, ‘Get here right away, Mr. Jackson had a bad reaction. Get somebody up here immediately,”’ Williams said.

Williams testified that he called Jackson’s bodyguard, Alberto Alvarez, who was outside, and told him to get up to the 2nd floor bedroom to check on Jackson.

Williams said Jackson had previously given strict orders that only Jackson and the children were allowed on the 2nd floor of the mansion.

“I told [Alvarez], ‘I don’t know what’s going on, but you have to go inside the house,'” said Williams. “I remember him walking, and I said, ‘Are you there, yet.’ He said, ‘No.’ I said, ‘Well run, hurry.‘”

Williams said he arrived at the mansion about 30 to 40 minutes later, in time to see Jackson being loaded into an ambulance.

“It was real frantic,” Williams said. “I got there and saw the gurney coming down the stairs. I remember seeing (Murray) talking to medics.”

He said after learning that Jackson had been pronounced dead, he and Murray stood in a hallway making small talk about how horrible the situation was.

He said Murray begged him for a ride back to the mansion to remove Jackson’s bleaching cream from his bedroom.

“He said ‘there’s some cream in Michael’s room that he wouldn’t want the world to know about,'” said Williams. “He requested that I give him a ride back to the house so the world wouldn’t know about the cream.”

Williams said he denied Murray’s request to give him a ride back to the mansion. He said he told Murray a story about the police taking his keys.
