The man whose body was exhumed from a shallow grave in a Rio Linda field last month has been identified as 69-year-old Larry Edward Lillard of Wheatland, according to the Sacramento County Coroner's Office.
Lillard's remains were found Aug. 27 after a tip prompted a search of a field in the 7500 block of 34th Street. Search and rescue dogs alerted authorities to the grave.
Sacramento County sheriff's Sgt. Jason Ramos said it appears Lillard had been dead for several months. He had been reported missing from Wheatland earlier this year.
Detectives are not sure whether Lillard was killed at the site, or how exactly he was killed, pending toxicology tests.
The District Attorney's criminal complaint against the man accused of killing Lillard, however, states that William Patrick Olsen, 47, used a ligature during the killing.
Initial information provided to law enforcement matched what was found at the scene, and further investigation led detectives to identify Olsen as the suspect, Ramos said. Olsen, who already was in custody on suspicion of car theft, was additionally booked on a murder charge the same day the body was found.
He was arraigned Aug. 30 and appointed a public defender, according to Superior Court records.
Lillard and Olsen were not related but had known each other for many years, according to detectives. The motive for the killing is unknown.
