Death of Michael Jackson  On June 25, 2009, American singer Michael Jackson died of acute propofol and benzodiazepine intoxication at his home on North Carolwood Drive in the Holmby Hills neighborhood of Los Angeles. Physician Conrad Murray said that he found Jackson in his room not breathing and with a weak pulse; he administered CPR to no avail, and security called 9-1-1 at 12:21 p.m. PDT (UTC–7) Paramedics treated Jackson at the scene, but he was pronounced dead at the Ronald Reagan UCLA Medical Center. On August 28, 2009, the Los Angeles County Coroner concluded that Jackson's death was a homicide. Jackson had been administered propofol and anti-anxiety benzodiazepines lorazepam and midazolam by his doctor. Murray was convicted of involuntary manslaughter in 2011 and served two years of his four-year prison sentence for good behavior. Jackson's death triggered reactions around the world, creating unprecedented surges of internet traffic and dramatically boosting sales of his music. He had been preparing for a series of comeback concerts at London's O2 Arena from July 2009 to March 2010. The Michael Jackson memorial service was held on July 7, 2009 at the Staples Center in Los Angeles where he had rehearsed for the London concerts the night before his death. It was broadcast live around the world, attracting an estimated audience of one billion people. Magician Ed Alonzo said that Jackson arrived for rehearsal at the Staples Center around 6:30 p.m. Pacific Daylight Time on Wednesday, June 24. Jackson jokingly complained of laryngitis and did not rehearse until 9 p.m. "He looked great and had great energy," Alonzo said. The rehearsal went past midnight. The next morning, Jackson did not come out of his bedroom. Jackson's physician Conrad Murray entered the room that afternoon and found Jackson in bed and not breathing. He had a weak pulse and was still warm. Murray tried to revive him for five to ten minutes, at which point he realized that he needed to call for help. Murray stated that he was hindered because there was no land-line telephone in the house. He also stated that he could not use his cell phone to call 911 because he did not know the exact address. He stated that he also phoned security, but got no answer. Murray ran downstairs, yelled for help, and told a chef to bring security up to the room. Murray's lawyer stated that at least 30 minutes passed before security made the phone call.
