On March 23, Nashville police confirmed to local NewsNation affiliate WKRN that Strain’s preliminary autopsy had been completed and his death appeared to be an accident pending toxicology reports, with “no foul play-related trauma” present.

Strain’s family, however, ordered a second autopsy and is continuing to look for other evidence that may shed light on what happened to him.
