In July of 1986, a 19-year-old man was found hanging from a tree near his Maryland home. Authorities swiftly ruled it a suicide, but those closest to him questioned everything about the scene; from the small tree, which could barely support his weight, to the lack of an autopsy, to the suspicious friends who seemed to vanish in the wake of his sudden death. Years later, his mother received a suspicious envelope on her doorstep, and new evidence would challenge the original ruling. This is the death of Keith Warren.
