The son of a prominent Hollywood producer was found dead in his jail cell over the weekend, just days before a scheduled court hearing in his triple murder case, authorities confirmed.

Samuel Bond Haskell IV, 36, was discovered Saturday morning in an apparent suicide, according to law enforcement sources cited by NBC Los Angeles.

His death was confirmed on Monday by Lt. Michael Modica of the Los Angeles County Sheriff’s Department, just hours before Haskell was due in court for a preliminary hearing in his case.

Haskell had been charged in the grisly 2023 murders of his wife, 37-year-old Mei Li Haskell, and her parents, Gaoshan Li, 72, and Yanxiang Wang, 64, at their home in Tarzana in November 2023.

The remains of Haskell’s in-laws have never been recovered.

Haskell pleaded not guilty and was being held without bail while awaiting trial.
