Jackson bodyguard says doc told him to hide vials

Alberto Alvarez said Dr. Conrad Murray grabbed the vials form a nightstand next to Jackson, who was still in his bed. ``He said here, put these in a bag.'' Alvarez said of Murray.

Alvarez said at first he thought he was bagging the items in preparation for a trip to the hospital. He said he trusted Murray because he was a doctor.

When he entered the bedroom, Alvarez said, he saw Jackson's eyes were open and was surprised to see the singer was wearing a condom catheter.

Alvarez testified that Murray only told him Jackson had a bad reaction. Alvarez is the sixth witness to testify in the involuntary manslaughter trial of Murray, who has pleaded not guilty.

Earlier, Alvarez testified that Jackson was in good spirits at a rehearsal on the night before he died.

``He was very happy,'' Alvarez testified. ``I do recall he was in very good spirits.''

Prosecutors have been calling witnesses who were with Jackson and Murray the day the singer died.

Authorities accuse Murray of giving Jackson a lethal dose of the anesthetic propofol in the bedroom.

Prosecutors are calling key witnesses in an attempt to show Murray delayed calling authorities on the day the King of Pop was found lifeless and was intent on concealing indications that he had been giving the singer doses of the surgical anesthetic.

The jury has already gotten a glimpse into the entertainer's inner sanctum through photos and testimony.

Alvarez's testimony will likely be challenged by Murray's defense attorneys, who on Wednesday questioned Jackson's head of security and the singer's personal assistant about why they didn't reveal certain details about the day Jackson died to police for at least two months.

Defense lawyer Ed Chernoff asked Faheem Muhammad and Michael Amir Williams about whether they conferred with Alvarez before their interviews with detectives.

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 emergency services.

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,'' prosecutor David Walgren asked

``That his eyes were open,'' Muhammad said. ``That his mouth was slightly open.''

``Did he appear to be dead,'' Walgren asked.

``Yes.''

The bodyguard soon noticed that Jackson's children, Prince and Paris, had gathered by the doorway.

``Paris was on the ground, balled up crying,'' Muhammad said. He ushered the children out of the room, and then into a sport utility vehicle so they could follow the ambulance to the hospital.

Some of the scenes recounted by Muhammad will likely be repeated Thursday as prosecutors work to fill in other details about Murray's behavior after finding Jackson unconscious. 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.

Much of the trial in later sessions will focus on the science of what killed Jackson, and dueling theories of Murray's role.
