A medical examiner determined that Campbell's cause of death was an ax wound to the neck.

Authorities say he stashed the body in his bedroom closet for a week before it was discovered.  All the while, they say Barth was going to work as a cook in a restaurant and telling friends that he had no idea what had happened to Campbell.
