LOS ANGELES — California prosecutors gave a chilling account of how a Hollywood producer allegedly drugged two young women, watched them die — and told a witness that “dead girls don’t talk” before dumping their bodies outside Los Angeles hospitals.

David Brian Pearce, the self-proclaimed Hollywood producer charged with the murder of Christy Giles and Hilda Marcela Cabrales-Arzola, awaited his fate Tuesday as a Los Angeles jury reached a verdict in his murder trial.
