Revealed: What happened minutes before Michael Jackson died

Micheal Jackson's personal assistant gave an emotional account in court Wednesday of the frantic moments after the singer's death.

Michael Amir Williams said Jackson's doctor, Conrad Murray, left him a panicked sounding voice message saying "please call me" after finding his patient not breathing.

Mr Williams told the court he was in the shower and missed the call from Dr Murray, who denies a charge of involuntary manslaughter over the 50-year-old singer's death just after midnight on June 25, 2009.

The message said: "Call me right away call me right away. Thank you."

Mr Williams phoned back two minutes later and, in a 35-second call, was told by Dr Murray: "Get here right away. Mr Jackson had a bad reaction. Get somebody here immediately."

He said Dr Murray did not asked him to phone the emergency services.

Mr Williams said he rushed to Jackson's home. He said: "When I got there they were beginning to bring the gurney down. It was real frantic."

He described Dr Murray as looking "frantic," adding: "I knew it was serious."

Mr Williams followed the ambulance in a car along with Jackson's three children Prince, Paris and Blanket, the court heard. He described shielding the children from television cameras.

He said Dr Murray asked him at the hospital to take him back to Jackson's house to recover a cream that, the doctor said, Jackson would "not want the world to know about". Mr Williams said he did not want to bring Dr Murray back to the house, and ordered security staff to "lock down" the premises.

In a search of Jackson's home after his death, police found two types of skin cream commonly used to treat vitiligo, a skin condition in which there is a loss of brown pigment, resulting in white patches.

Dr Murray is accused of administering a lethal dose of the anaesthetic propofol, and other sedatives, in an attempt to help Jackson sleep.

Earlier, Los Angeles Superior Court heard that Dr Murray had asked the promoters of Jackson's planned comeback tour for life-saving equipment to help him care for the singer, days before his death.

A lawyer who drew up a "contract of services" between Jackson, Dr Murray and the promoters AEG Live, said the request was for a portable cardiopulmonary resuscitation (CPR) machine.

Kathy Jorrie said she had been surprised by the request for a CPR machine and queried Dr Murray over it.

"He said that, given [Jackson's] age and the strenuous performance, he needed to be sure that if something went wrong he would have the machine," she said.

She added: "Dr Murray told me repeatedly Michael Jackson was perfectly healthy and in excellent condition."

The machine and extra doctor were not delivered because Jackson had not signed the contract before he died.

Miss Jorrie said she also passed on to Dr Murray a request from insurers to see Jackson's medical records. The doctor told her there had been no major health issues so his medical records would be "tiny". Miss Jorrie said she had spoken to Dr Murray on the phone the day before the singer died. Dr Murray told her he had watched Jackson rehearsing and that he looked "extraordinary."

According to Paul Gongaware, a music executive who witnessed the singer practicing on the two days before his death, Jackson appeared "strong" and "full of energy" at rehearsals.

Mr Gongaware, the joint chief executive of AEG Live, also said Dr Murray had a "friendly and caring" relationship with Jackson. He said he had "no idea" the doctor was giving Jackson nightly doses of propofol. Under cross-examination, Mr Gongaware acknowledged that AEG is being sued by Jackson's mother Katherine for alleged negligent supervision of Dr Murray when he worked with the singer.
