A Hollywood producer murdered a model and her friend with a cocktail of drugs. His sister has a message for their families

A night out in Los Angeles ended in tragedy when the bodies of two women were dumped outside area hospitals. Christy Giles was dead. Her friend Hilda Cabrales-Arzola was barely alive. David Pearce, the Hollywood producer who partied with them that night, was later charged with their murders, accused of providing the women with a cocktail of drugs. Now, a jury has found him guilty. His sister tells Andrea Cavallier it’s what he deserves – and says she wants the victims’ families to know that she’s sorry for his actions
