The Los Angeles man arrested after a homeless man found a headless body in a dumpster is the scion of a prominent Hollywood family whose wife and in-laws are missing.

The Los Angeles Police Department said Wednesday that they responded to a dumpster near Ventura Boulevard and Rubio Avenue in Encino around 6 a.m. and recovered a woman's headless torso.

Police said they found evidence at the scene that led them to the Tarzana home of Sam Haskell IV, 35, the son of Hollywood producer Sam Haskell III.

The younger Haskell lived there with his wife, three children and in-laws. The children are OK, according to authorities.

But his 37-year-old wife, Mei Haskell, and her parents, Goashan Li, 72, and Yanxiang Wang, 64, are unaccounted for, authorities say. LAPD Detective Efren Gutierrez told reporters during a news briefing attended by FOX 11 Los Angeles that attempts to contact all three were unsuccessful.

Police said the recovered remains had not yet been identified, but they may belong to Mei. Investigators found blood and other evidence in the home.

Haskell's famous dad was a longtime A-list talent agent who represented stars like Dolly Parton and George Clooney before becoming an Emmy-winning producer. He received four Emmy nominations and a single win for teaming up with Parton on "Christmas on the Square."

He was also a longtime Miss America Organization CEO who was embroiled in a scandal after leaked emails showed him disparaging former winners.

His fall was chronicled in A&E's "Secrets of Miss America" miniseries in June, which included allegations of the elder Haskell sabotaging the career opportunities and romantic lives of pageant winners.

His son, meanwhile, used to maintain an Instagram account where he frequently posted about his Hollywood lifestyle under the hashtag #richkids.
