A Michigan man says he was "stunned" to learn DNA testing disproved his suspicion that he was kidnapped as a toddler in New York state in 1955.
John Barnes had said he believed the test would confirm he was Stephen Damman, who disappeared at age 2 in East Meadow, N.Y.
He suspected the couple who raised him weren't his biological parents.
But DNA results released last week showed there was no way he could be the kidnapped child.
The unemployed laborer who lives in rural northwest Michigan told the Detroit Free Press he "was disappointed, kind of stunned" by the news.
He said he "really thought I was that kid."
Barnes did not immediately respond to an Associated Press call seeking comment Tuesday.
