The decision to shut down the investigation comes just weeks after cops in Utah received and reviewed Coleman's autopsy report -- in which the coroner labeled Gary's death an "accident."
Indeed the autopsy concludes Coleman was in terrible shape before he died. A rep for the Santaquin Police tells us, "[Gary] was an accident waiting to happen. The last time I saw him he literally looked gray.”
FYI -- no one was ever suspected of killing Gary ... but his kinda-sorta wife Shannon Price did release an unsolicited statement denying any involvement in Coleman's death.
