Jury selection recently began in the case against Michael Jackson’s former physician, Dr. Conrad Murray. More than 300 jurors are being screened for the case’s court proceedings which began Thursday…

Los Angeles Superior Court Judge Michael E. Pastor will ask potential jurors several questions, including if participating in the 45-day trial will be financially feasible. Once the screening process ends, jurors will then return to the courthouse early May, to fill out a confidential 27-page questionnaire.

Murray, who is being tried for injecting Michael Jackson with anesthesia Propofal, may face up to four years in prison if convicted. Although a coroner’s report confirmed the pop-star’s death was a result of “acute Propofal poisoning,” Murray still says he’s innocent. The doctor plans to argue that Jackson injected himself with the lethal drug the night before his death.

Opening statements for the trial are set to begin May 9.
