The coroner’s report also determined he had been struck multiple times with an unidentified object.

The car Burchard’s body was found it belonged to Turner, a former model, who had never reported it missing.

Burchard had been reported missing by his longtime girlfriend in California when he didn’t return home.

She told police that he had gone to visit Turner and she became concerned when she started receiving text messages that didn’t sound like Burchard.

She believed Turner and her boyfriend may have killed him, the report said.
