LOS ANGELES (AP) - Michael Jackson's brother says it's believed that the pop star died of cardiac arrest.
Jermaine Jackson cautioned at a hospital news conference in Los Angeles that the cause of death won't be known until an autopsy is performed.
He said Michael Jackson's personal doctor and paramedics tried to resuscitate Jackson at his rented home in Holmby Hills, not far from the UCLA Medical Center. A team of doctors there also tried for more than an hour.
Los Angeles police Lt. Gregg Strenk told a separate news conference that police robbery-homicide detectives have been ordered to investigate, which is a common practice in a high-profile case. Strenk says the coroner's office is taking possession of the body.
