Man abducted as a baby searching for true identity after being raised by wrong parents

At the age of 49, Paul Fronczak discovered the parents who raised him were not his biological relations and the name he grew up with was not his own.

His parents had been involved in an abduction case nearly half a century ago, and Fronczak's DNA test proved police had returned the wrong baby, according to Sky News.

The revelation has lead the FBI to reopen this painful case, which began with the birth of a baby boy at the Michael Reese Hospital in Chicago in 1964. A woman dressed as a nurse walked into the room 16 hours after Paul Joseph Fronczak was born, according to CBS New York, and said she needed to take the baby.

The woman picked up the baby and never returned, and neither has the child the Fronczak's lost that day.

But two-and-a-half years later, the FBI received word of an abandoned baby found in New Jersey. Investigators determined his ears matched those of the abducted child and so they brought him to the Fronczaks, according to CBS.

That child has told media he's now searching for his identity, hoping also to find the baby that really went missing nearly 50 years ago.
