David Brian Pearce's crimes: A complete timeline of events
Hollywood producer David Brian Pearce was convicted of multiple charges in February 2025, including first-degree murder and s*xual assault. His conviction was reached after a prolonged investigation, which began when model Christy Giles and architect Hilda Marcela Cabrales-Arzola passed away in November 2021.
The case revealed a history of crime dating back to 2007, where several women claimed that Pearce had s*xually assaulted them. Authorities linked Pearce to a series of drugging and assault cases, which later led to his arrest. Initially, he was accused of manslaughter, but was later charged with first-degree murder when forensic reports and witness statements yielded more evidence.
His trial, which took place in early 2025, resulted in a guilty verdict. Pearce is now facing 148 years to life in prison. David Pearce's case will be showcased on CBS's 48 Hours in an episode called Dead Girls Don't Talk. It will air on Saturday, March 29, 2025, at 10 pm ET/PT.
