Michael Jackson's death was ruled a homicide, according to the Associated Press on Monday citing a law enforcement official speaking under the condition of anonymity.

The ruling from the Los Angeles County coroner makes it more likely that criminal charges will be filed against the doctor who was with Jackson when he died, the Associated Press reports.

Dr. Conrad Murray is the target of a manslaughter probe headed by Los Angeles police.

When Jackson died on June 25 he had lethal levels of the powerful anesthetic propofol in his body.
