Dr. Conrad Murray

*The man who called 911 as Michael Jackson lay dying in his rented mansion told police he was stunned by what he saw in the singer’s bedroom.

Alberto Alvarez, who worked as Jackson’s logistics director, told investigators that after receiving a distress call from another worker June 25, he rushed up the stairs of Jackson’s home and entered a bedroom to find the singer lying on a bed with his arms outstretched and his eyes and mouth open.

At his side, Jackson’s personal physician, Dr. Conrad Murray, was administering CPR with one hand.

“Alberto, Alberto, come quickly,” Murray said, according to a statement obtained by The Associated Press. “He had a reaction, he had a bad reaction.”

Two of the star’s children, Prince and Paris, came in the room and cried as they saw Murray trying to save their father. They were quickly ushered away.

The account and other statements obtained by the AP depict a grisly scene in Jackson’s room in the final minutes before paramedics arrived. Alvarez also states that Murray interrupted CPR and delayed calling paramedics so he could collect drug vials at the scene.

Jackson’s death at age 50 was ruled a homicide caused by an overdose of the powerful anesthetic propofol and other sedatives.

The possibility that Murray may have tried to hide evidence is likely to be a focus as prosecutors move ahead with their involuntary manslaughter case against him.
