<p><br /> Members of Michael Jackson's family have arrived at a Los Angeles Superior Court to attend the first day of hearings on whether to proceed with a trial against the late singer's physician, Conrad Murray.<br /> </p><p><br /> Murray is charged with involuntary manslaughter in the death of pop star Michael Jackson.<br /> </p><p><br /> Prosecutors are expected to begin offering evidence that Murray is responsible for the singer's death in a case that could hinge on who gave the singer a fatal dose of a powerful drug he used for sleep.<br /> </p><p><br /> Murray arrived at the courthouse for the hearing in a black Mercedes and was escorted into the building away from the media through an underground entrance.<br /> </p><p><br /> Jackson, one of the best-selling recording artists of all time who generated hits like Thriller and Billie Jean, died of a prescription drug overdose on June 25, 2009, at age 50, after suffering cardiac arrest while in bed at his rented mansion.<br /> </p><p><br /> Murray has admitted injecting Jackson with the powerful anesthetic propofol, which has been determined to be a key factor in his death. The drug is used mostly in hospital settings, but it was given to Jackson at home as a sleep aid.<br /> </p><p><br /> Prosecutors hope to paint the doctor, who was hired by a concert promoter to care for Jackson before a series of performances, as a man who was in financial trouble and would irresponsibly give the singer drugs to keep his paycheck.<br /> </p><p><br /> Murray has pleaded not guilty, and last week defense attorneys indicated they may focus on a mysterious syringe found near Jackson to explore whether someone other than Murray injected the singer with the fatal dose of propofol.<br /> </p>
