LOS ANGELES (AP) - Prosecutors hope to use a key witness today to help show that Michael Jackson's doctor delayed calling authorities on the day the King of Pop died.
Prosecutors also hope the testimony of bodyguard Alberto Alvarez will bolster the theory that Dr. Conrad Murray was intent on concealing indications that he had been giving the singer doses of a powerful surgical anesthetic.
The third day of Murray's involuntary manslaughter trial is expected to keep jurors focused on events in Jackson's bedroom during the frantic moments when efforts were made to revive the unresponsive pop superstar. The bodyguard's testimony is considered crucial to prosecutors' contentions that Murray delayed calling 911.
