In New York, police told one couple that their son had died in a car wreck -- only he was still alive. The teen's brother found him sleeping at their house. The parents spent about 90 minutes thinking they had lost a son. The dead man was actually a fraternity brother of the teen, and for some reason, he had a copy of the teen's license with him when he died.
This isn't the first time something similar has happened. In 2006, everyone thought Whitney Cerak had died in a crash with other students, but she was actually alive. Her injuries were so severe, officials confused her with a girl who had died, Laura VanRyn.
