The Los Angeles County Coroner has determined that Michael Jackson died of acute propofol intoxication, with a handful of other drugs also contributing to the singer's death.
The coroner's office officially ruled the death a homicide.
"The drugs Propofol and Lorazepam were found to be the primary drugs responsible for Mr. Jackson's death," the coroner's office said in a statement Friday. "Other drugs detected were: Midazolam, Diazepam, Lidocaine and Ephedrine."
The other drugs listed are benzodiazepines typically used to treat anxiety and insomnia.
The Jacksons issued a statement following the coroner's release: "The Jackson family again wishes to commend the actions of the Coroner, the LAPD and other law enforcement agencies, and looks forward to the day that justice can be served."

What Is Propofol?
Law enforcement sources previously told FOXNews.com that Jackson's personal physician, Dr. Conrad Murray, admitted he gave the singer, 50, the intravenous anesthetic propofol to help him sleep just hours before his death.
A law enforcement source told FOXNews.com that Murray would be charged with manslaughter in Jackson's death. A spokeswoman for the Los Angeles County District Attorney's office denied that prosecutors had decided to charge Murray.
At the request of the Los Angeles County District Attorney and the Los Angeles Police Department, "the final Coroner's report, including the complete toxicology report will remain on Security Hold" until their investigations are complete, the coroner's statement said.

The coroner's statement was released as the heat is being turned up on Jackson's longtime friend and dermatologist Arnold Klein, who investigators believe facilitated the singers' years-long drug abuse.

According to the warrant and affidavit for last Friday's raid on Mickey Fine Pharmacy in Beverly Hills, Calif. investigators were searching for records of medication Klein allegedly prescribed to himself then gave to Jackson.

The return — a list of items seized during the search — was filed Thursday evening in California federal court and shows that investigators seized, "60 prescriptions, 29 patient profile print-outs, three copies of DEA Forms 222 (Order Forms) and copies of inventories of controlled substances."
Law enforcement sources told FOXNews.com that Friday's search of the Beverly Hills pharmacy yielded records of Klein prescribing controlled substances to himself.
According to the warrant for inspection and the affidavit for administrative inspection warrant, both obtained by FOXNews.com, between January 1, 2008 and July 6, 2009, Klein self-prescribed 27 controlled substances, which he filled at Mickey Fine Pharmacy and which investigators believe he gave to his friends — including Michael Jackson, who died of an apparent drug overdose on June 25.
The 60 prescriptions and 29 patient profiles were all related to the investigation into Jackson's death. The patient profiles belong to Jackson and aliases used by the star, law enforcement sources told FOXNews.com.
Investigators used the Controlled Substance Utilization Review and Evaluation System (CURES), a database of all schedule 2 through 4 drugs prescribed by doctors or dispensed by pharmacies or medical facilities in the state of California.
According to the affidavit: "The [CURES] report shows 27 prescriptions written by Dr. Klein in a self-prescribing capacity, specifically prescribing medication to himself, from March 2006 through May 2009. These prescriptions include the medications hydrocodone (Vicodin), modafinil (Provigil), diazepam (Valium), and injectable midazolam (Versed)."
A CURES report for the pharmacy revealed the same self-prescribing information found in Klein's report.
The day after FOXNews.com reported exclusively that Klein was the subject of a criminal investigation likely to culminate in charges related to medical malpractice, Klein's criminal attorney told the DEA that the dermatologist had never self-prescribed.

Self-prescribing controlled substances is in violation of California Health & Safety Code 11170 —but it is not a criminal act.
The penalties for self-prescribing include fines and a loss of a physician's DEA license to prescribe controlled substances.
In the coming weeks, investigators will focus on obtaining more records of Klein's prescribing history, law enforcement sources tell FOXNews.com.
