It was the Thursday after Mother's Day. A group of teenagers on Park Avenue in Philadelphia saw something large, wrapped in blankets on the back seat of a white Pontiac.

A few days earlier, Melvin Dunn's family sent out a desperate plea for help. Melvin had missed Mother's Day for the first time ever, and they couldn't find him. 

If you have any information about what happened to Melvin Dunn, contact the Philadelphia Police Department.
