LOS ANGELES (AP) -- Michael Jackson's former personal assistant says he fielded an urgent phone call from the doctor charged in the singer's death but was never told to call 911.
Michael Amir Williams told jurors that defendant Dr. Conrad Murray simply told him that Jackson had a bad reaction.
Williams dispatched a security guard to the bedroom of Jackson's rented mansion, where Murray had been giving the singer the anesthetic propofol as a sleep aid.
Authorities contend the Houston-based cardiologist gave Jackson a lethal dose of the anesthetic and other sedatives. Murray's attorneys claim Jackson gave himself the fatal dose while the doctor was out of the room.
