Just hours after court documents were unsealed indicating that Michael Jackson had lethal levels of the drug propofol in his system, an unnamed law-enforcement official reportedly told The Associated Press that Jackson's death has been ruled a homicide by the Los Angeles County coroner.

The coroner determined a fatal combination of drugs was given to Jackson hours before he died on June 25, according to the official, who spoke on condition of anonymity because the findings have not been publicly released, the AP reported. Forensic tests indicated that propofol acted with at least two sedatives to cause Jackson's death, according to the official.

The court documents unsealed on Monday indicated that Jackson's private physician, Dr. Conrad Murray, informed investigators he administered 25 milligrams of propofol to Jackson at 10:40 a.m. as the singer struggled to fall asleep after previously giving him the sedatives lorazepam and midazolam.

Murphy is currently under a manslaughter investigation by the LAPD, and the AP reported that Monday's information is likely to increase the chances that criminal charges will be filed against Murray.

Just hours after the documents were released — which are not the official coroner's report — a representative for the Jackson family released the following statement: "The Jackson family has full confidence in the legal process, and commends the ongoing efforts of the L.A. County Coroner, the L.A. District Attorney and the L.A. Police Department. The family looks forward to the day that justice can be served."

According to the Los Angeles Times, the warrant revealed Murray told investigators that he had been treating Jackson for insomnia for six weeks and had been giving Jackson 50 milligrams of propofol each night with an IV and was afraid the Jackson was developing an addiction to the drug and that he was trying to wean him off of it.

In a videotaped message last week, Murray said: "I have done all I could do. I told the truth, and I have faith that truth will prevail."
