LOS ANGELES, California (CNN) -- The Los Angeles County coroner has ruled that Michael Jackson's death was a homicide involving a combination of drugs.

Michael Jackson was found dead on June 25. He had been preparing for a comeback concert series in London.

"The drugs propofol and lorazepam were found to be the primary drugs responsible for Mr. Jackson's death," said a news release issued Friday by the coroner. "Other drugs detected were: midazolam, diazepam, lidocaine and ephedrine."

The release said Jackson died from "acute propofol intoxication," but said "other conditions contributing to death: benzodiazepine effect."

About 1:30 a.m., Murray gave Jackson 10 mg of Valium (diazepam).

• About 2 a.m., he injected Jackson with 2 mg of the antianxiety drug Ativan (lorazepam).

• About 3 a.m., Murray then administered 2 mg of the sedative Versed (midazolam).

• About 5 a.m., he administered another 2 mg of Ativan.

• About 7:30 a.m., Murray gave Jackson yet another 2 mg of Versed while monitoring him with a device that measures the oxygen saturation of his blood.

• About 10:40 a.m., "after repeated demands/requests from Jackson," Murray administered 25 mg of propofol, the document said.

"Jackson finally went to sleep and Murray stated that he remained monitoring him. After approximately 10 minutes, Murray stated he left Jackson's side to go to the restroom and relieve himself. Murray stated he was out of the room for about two minutes maximum. Upon his return, Murray noticed that Jackson was no longer breathing."
