Documents released Monday show that Murray administered a continuous cocktail of sedatives the morning Jackson died in an effort to put the singer to sleep. It was the propofol, a powerful anesthetic typically used in operating rooms, that caused him to stop breathing, according to the report.

Jackson's death was ruled a homicide.

"The Los Angeles Chief Medical Examiner-Coroner, Dr. Lakshmanan Sathyavagiswaran, indicated that he had reviewed the preliminary toxicology results and his preliminary assessment of Jackson's cause of death was due to lethal levels of propofol (Diprivan)," according to the search warrant affidavit.
