#17 Walter Collins
In 2008, the movie Changeling brought back a strange tale from the 1920s. A single mother, Christine Collins, reported Walter Collins, her son, missing. Walter went missing in the month of March 1928.
Just five months after his disappearance, the LAPD brought back a child claiming him to be Walter. However, Christine knew that it was not her son.
Even years later, the real Walter was never found, and no one ever learned of why the police replaced his identity with another child.
