A former rock musician faces murder charges over the death of his missing girlfriend in California following the discovery of human remains.

Theobald Lengyel, 54, was arrested in connection with the killing of 61-year-old Alice “Alyx” Kamakaokalani Herrmann. Police say she was last seen alive in Santa Cruz on 3 December.

Herrmann was reported missing by her family on 12 December and her Toyota Highlander vehicle was found outside her boyfriend’s home in El Cerrito.

Mr Lengyel was a founding member of the funk-metal band Mr Bungle and played a variety of instruments, according to SFGate.

Officials said that following the victim’s disappearance he had “not cooperated with the police investigation” and travelled by car to Portland, Oregon.

Investigators eventually found human remains in a wooded area at Tilden Regional Park, around four miles from El Cerrito.

Police have not shared any details on the cause of death and the remains are awaiting DNA confirmation by the Contra Costa County Coroner’s Office.
