Police continued to investigate what they believe to be the discovery of a human skull and partial skeletal remains buried beneath the yard of a Buena Park home on Monday.
Early Sunday evening, a man who lives on the 8200 block of Commonwealth Avenue was digging a fire pit in his yard, police say, according to NBC L.A. When he came across bones in the dirt several feet below the surface, the man notified the Buena Park Police Department.
Police then notified the Orange County Coroner's Office and brought in a cadaver dog to search for additional remains, according to a police statement. None were found as of Monday afternoon.
The Coroner's Office collected the remains on Monday for further examination, but declined to comment any further on the investigation or provide further details.
Investigators plan to enlist officials from the Native American Heritage Association to examine the discovery and determine if the bones are of Native American origin, police say, according to NBC L.A.
Information was not publicly available on how long the bones were buried, the number of bones found on the property or the status of forensic testing, Buena Park Police Sgt. Mike Lovchik told KPCC, adding that, in many cases, "human" bone discoveries turn out to be animal remains.
"At this point in the investigation, there doesn't appear to be any criminal activity involved," Lovchik said. "There could be any number of possibilities [of where these came from]."
The man who discovered the bones has been cooperating with the investigation and is not being treated as a suspect, Lovchik said.
