The involuntary manslaughter trial of Michael Jackson's doctor, Conrad Murray, got under way in Los Angeles on Tuesday.
Murray is accused of killing the superstar on June 25, 2009, by giving him propofol, a powerful anesthetic he had been administering to the singer the past two months to help Jackson sleep.
District Attorney David Walgren depicted Murray in his opening statement as a reckless medical professional who was only interested in money and fame.
Defense lawyer Ed Chernoff contends Jackson, desperate for sleep, caused his own death by taking a handful of sedatives and drinking propofol while Murray was out of the room.
Murray appeared to become emotional at one point as Chernoff presented his opening statement, but has mostly remained stoic during the proceedings.
Michael Jackson supporters thronged outside the courtroom. Many carried signs, some sunflowers, while a Jackson impersonator even performed at one point.
Supporters of Murray also gathered outside the courthouse.
Prosecutors presented several dramatic photos, including one of Jackson's lifeless body on a gurney and this one of the interior of his bedroom.
Jurors also heard a stunning audio recording made by Murray of a drugged Jackson slurring his words weeks before his death.
Producer Kenny Ortega told jurors he was jolted by Jackson's appearance when the singer arrived at a rehearsal for his "This Is It" tour on June 19, less than a week before he died.
Paul Gongaware, an executive with the firm promoting the concert, hired Murray as Jackson's doctor for $150,000 a month. He said Murray had wanted $5 million a year.
Janet Jackson is seen leaving the courthouse after the first day of testimony. She and Jackson's parents, brothers Tito, Jermaine and Randy, and sisters La Toya and Rebbie filled a row in the courtroom for opening statements.
Jackson's three children are not expected to attend the trial or testify, according to a source close to their grandmother, Katherine Jackson.
