A newborn baby who was abducted in 1964 from a Chicago hospital has been located living under a different name.

Paul Fronczak, who was found in rural Michigan, was snatched from Michael Reese Hospital more than 55 years ago, news station WGN-TV reported.

Fronczak was only 1 day old when a woman posing as a nurse entered his mother’s hospital room and claimed she needed to bring the infant to a doctor, only to never return with the newborn, the report said.

The FBI launched a search for the missing child that appeared to come to a happy ending two years later.

A baby was found abandoned in New Jersey with ears similar to parents Chester and Dora Fronczak’s missing son, WGN-TV reported.

Though there was little evidence linking him to the case, the couple adopted the child and raised him as their own. However, he took a DNA test decades later that proved he wasn’t related to the couple, news station KLAS-TV reported.

But several months ago, the FBI located the other Paul Fronczak in rural Michigan and informed him of his real identity, WGN-TV reported.

The man, who didn’t want to be identified by his new name, said he’s still coming to grips with the news of his abduction.

“I have loose ends to tie up,” the man told the outlet.

He declined to comment on whether he planned to meet his biological mother, who lives in the Chicago suburbs. His father, Chester, died several years ago, according to the report.

The FBI declined to confirm whether the case has been solved.

“Several years ago, the FBI reopened the investigation into the disappearance of Paul Joseph Fronczak,” an FBI Chicago spokesperson told WGN-TV. “Our investigation into this matter remains ongoing as we continue to pursue all leads. We ask for privacy for the victims as we continue to investigate the facts surrounding this case.”
