mr. holton did shoot his wife and then turn the gun on himself, why such a bizarre way to do that? ext morning a state pathologist confirmed michael holton had a close contact wound at the base of his head. and to investigators the angle seemed telling. >> the only way we were able to do that is hold a gun upside down and place it upside down and then angle it because, remember, the angle is upwards. >> upside down and using his left hand. the thing about that is michael holton was right-handed. normally when men commit suicide, they use their dominant hand. >> sure. >> not their weaker hand. >> that's right. >> to the sheriff and his investigators, that made suicide improbable, and the pathologist agreed. he classified michael holton's death a homicide. >> he does not believe that that man would have killed himself or would have been able to kill himself in that manner. >> and so you go forward with a homicide investigation. >> it's not a head scratcher. you get a piece of paper that says homicide. >> this was now a murder investigation, and if there were three people in that house
