When a well-liked young man lost his wife and son on a family outing, an entire town mourned. But there was somebody who suspected the tragedy was no accident.
He was the only one who could discover the truth - but also the one most afraid to do just that - because he was the widower's best friend.
NBC's Keith Morrison uncovers the Mystery at Lost Dog Road at 9 p.m. ET, 8 p.m. CT on Dateline Friday.
