William Patrick Olsen, 47, was already in jail on Tuesday when detectives added an additional charge of suspicion of murder. He had been booked Monday into Sacramento County Jail on an auto theft charge.
The homicide case began when Placer County Sheriff's Department detectives contacted Sacramento detectives on Monday about a buried body. According to an unnamed source, a body was buried in a field in the 7500 block of 34th Street in Rio Linda.
Sacramento homicide detectives went to the Rio Linda field Tuesday morning. Detectives were aided by dogs in the search for a cadaver.
The dogs performed well, helping detectives find a makeshift gravesite on the property. Personnel from the Sacramento County District Attorney's crime lab also responded to the scene.
The site was excavated and human remains were recovered, according to the Sacramento sheriff's department.
Initial information provided to detectives was consistent with what investigators found at the scene, according to a sheriff's department press release. Information obtained by investigators also included the name of a suspect.
Detectives performed follow-up investigation that they said corroborated the suspect information and led them to arrest Olsen.
Positive identification of the body has not been made. Detectives are looking into the possibility that the body may be that of a person reported missing from a community outside of Sacramento County.
The dead person's name will be released after notification of family.
