A teenager from Silver Spring, Maryland, was found hanging from a tree in 1986. Even though the teen was only one month away from starting college and seemed to have a bright future ahead of him, the police ruled his death a suicide.

Inside the envelope were official crime scene photographs that showed him wearing someone else’s clothing.
