49-year-old Paul Fronczak found out the hard way that the parents who raised him are not his real parents. The real Paul Fronczak who was abducted by a woman in a nurse's uniform back in 1964 from a Chicago hospital and he was never found since.

"I think that the perfect ending would be to find the real Paul, see that he's doing well and then on the same day find my real family," he told NBC.

Paul Fronczak has always wondered why he didn't look like his parents so he took a home DNA test a few months ago. The test proved that he is not the real Paul Fronczak and the folks he calls mom and dad are not his biological parents. The Fronczaks whose real son got abducted in 1964 received great news in 1965 -that their baby has been found. Little did they know that the baby found outside a variety store in Newark is not their son. Before the baby from the variety store was found by authorities, he was taken to an orphanage nearby. They named the boy Scott McKinley.

In an email to his parents, the baby who was named Scott McKinley before he became Paul Fronczak said, "Wouldn't you and Dad like to know what really happened, and who I really am?" he wrote. "Like I said, I love you both and you have been wonderful parents. I am not doing this to hurt you or discredit the fabulous job you both did in raising me ... This is just about finding out the truth!"

The FBI is now dusting off the Fronczak file. Joan Hyde for the FBI office in Chicago told reporters, "We decided it merited another look. The main thing is to look at physical evidence and see if technology and tests that weren't available when the case was originally worked could provide leads."
