so okay who is this mysterious caller and was he involved in causing the “accident”
That’s for Coconino County law enforcement to find out.
“so okay who is this mysterious caller and was he involved in causing the accident
How convenient to have an (almost) eyewitness to report no foul play involved in this “accident”.
Why is his death “mysterious”, other than his cause of death is still unknown.
Based on his age and the lack of another vehicle involved, a medical condition (ex: massive heart attack) while driving would have produced similar results.
Since the ME’s preliminary investigation didn’t note any gunshot and the lack of any major LE response (manhunt, etc.), it appears that initially, that this could be the conclusion.
Regardless of the cause, prayers to his family.
