SACRAMENTO — Two severed limbs and a head were found on Beer Can Beach in California's Sutter County over the weekend, according to authorities.

The first gruesome discovery was made Saturday evening, when two fishermen came across what appeared to be human remains at the river bottom area off Garden Highway and Lee Road, according to a news release from the Sutter County Sheriff's Department.

Deputies confirmed the remains were human — two severed limbs — and called in detectives to investigate. The investigation continued into Sunday, when detectives found a human head in bushes about six feet up a hill from where the remains had been found the day before, the release states.

The department called in cadaver dogs from the Sacramento County Sheriff's Department and the state Office of Emergency Services Search and Rescue team, but the six dogs did not find anything else.

A forensic exam is scheduled to determine whether the remains belong to a man or woman
