There was a case in SE Michigan about 15 years ago. A teenage boy was found tied to a tree. His story was that he and his girlfriend were in the park when they were accosted by a stranger with a gun. The stranger tied the teenager up, and abducted the girl. She was never found.
The teenager wasn't quite 18 years old, so the media did not release his name, but it was obvious that the police considered the teenager responsible, even though they lacked enough evidence to arrest him.
Two years pass. A young teenage girl darts out into the middle of the road, screaming that a man is chasing her. A motorist stops, rescues the girl, and sees enough of the license plate for the police to track down the man chasing her.
Once arrested, the man admitted to killing several teenage girls, including the one whose boyfriend he had tied to a tree. He even led the police to that girl's body.
What gave me chills about this story was that someone completely innocent, who had been subjected to a terrifying encounter with evil, was himself considered guilty for over two years. And it was only chance that exonerated him.
