"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. “It’s just an opportunity to look at this, give it a fresh look and perhaps re-interview witnesses,” said Joan Hyde, a spokeswoman for the FBI office in Chicago. We now have the ability to perhaps subject some of the physical evidence to new and previously unavailable forensic examinations.” 
 
 The Fronczak case was front-page news in the city and beyond, when a woman — disguised as a nurse — walked into Michael Reese on April 27, 1964, and told Dora Fronczak that her newborn was needed for an examination. Fourteen months later, a toddler abandoned in Newark, N.J., who resembled the missing child was returned to Fronczak's parents after an investigation by the FBI. The parents, who live in Oak Lawn, have previously declined comment on the turn of events and did not return a call for comment Wednesday. “I feel I am one step closer to solving these two tragic mysteries, and one step closer to a very happy ending!” 
 
 Still, Fronczak knows that his search is painful for his adoptive parents. The focus of the investigation centers on the kidnapping in Chicago, Hyde said, but may progress to involve the abandoned toddler in Newark.
– Paul Joseph Fronczak was abducted as an infant from a Chicago hospital in 1964; shortly afterward authorities thought they'd found him and returned a baby to Fronczak's parents. That child was raised as Paul Fronczak—but a DNA test this year shows it wasn't him. Now, the FBI is reopening the case, the Chicago Tribune reports. The man raised as Fronczak is hoping to find the kidnapping victim, not to mention his own birth parents. "I'm in this for the long haul," he says. "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 says. In 1964, a woman posing as a nurse told mom Dora Fronczak the baby needed an exam; the "nurse" and the baby disappeared in a taxi, the Chicago Sun-Times notes. Investigators thought they'd found the baby in New Jersey, identifying an abandoned child as Fronczak partially based on the shape of his ears. Now, the FBI hopes "new witnesses come forward," and it may "subject some of the physical evidence to new and previously unavailable forensic examinations," says a rep.
