Michael Jackson was an American singer, songwriter, dancer, and philanthropist, known as the "King of Pop". On June 25, 2009, Jackson died of acute propofol intoxication in Los Angeles, California, at the age of 50. His physician, Conrad Murray, found Jackson in his room at his North Carolwood Drive home in the Holmby Hills area of the city not breathing and with a weak pulse. Murray administered cardiopulmonary resuscitation (CPR) to no avail, and security called 9-1-1 at 12:21 p.m. Pacific Daylight Time (UTC–7). At the time of his death, Michael Jackson was preparing for a series of comeback concerts, This Is It, due to begin in July 2009 at Londons O2 Arena. Jackson died from an overdose of propofol administered by his personal physician, Conrad Murray, who was convicted in 2011 of involuntary manslaughter for his involvement in Jacksons death.
