Michael Jackson died June 25, 2009. He was found unconscious at his rented Holmby Hills estate in Los Angeles, where he was staying while preparing for a series of concerts in London. He was taken to Ronald Reagan UCLA Medical Center, where he was pronounced dead.

The coroner's office determined that the 50-year-old singer died of propofol intoxication, a powerful sedative, prescribed by his personal physician, Conrad Murray, who has been charged with involuntary manslaughter and is awaiting trial.

Jackson's death shocked the world and prompted a media frenzy. Thousands of fans swarmed his memorial service at the Staples Center in downtown Los Angeles. Weeks later, he was laid to rest at the Glendale cemetery.
