One-day-old Paul was stolen from Michael Reese Hospital in Chicago, Illinois on April 27, 1964 when he was only 36 hours old.
He is the second child of his parents Chester & Dora Fronczak; their first child was stillborn. Paul's abductor posed as a nurse, wearing a white uniform, but no cap.
At 9:30 a.m., the abductor came into Dora & Paul's hospital room while Paul was nursing, unwrapped his blanket, looked at him and then left without saying a word. At 1:30 p.m., she returned to the room and said that she needed to take Paul to the nursery & Dora gave him to her. Twenty minutes had passed before a real nurse came into the room to take Paul to the nursery and it was realized that he was missing.
At 2:00 p.m., the police were called after a search of the hospital turned up no sign of him. Investigators determined that the abductor took Paul down a back staircase, left the hospital through the rear entrance and took a cab to the vicinity of 35th and Halstead at which point, the trail was lost.
The abductor is described as 35 to 40 years old in 1964, of medium height with graying dark hair, brown eyes and a reddish complexion. The police believe that she had a good idea of the hospital layout and staff routines. The abductor was never identified or apprehended.
On July 2, 1965, a toddler was found abandoned outside a Newark, New Jersey store. The boy was named Scott McKinley by the New Jersey child protection authorities. Scott resembled Paul and was about the right age.
FBI agents tested Scott's blood and thought he might be the Fronczak's son, but since DNA testing was unavailable in the '60s and Paul's footprints had not been taken before he was abducted, they were unable to establish the identity of the abandoned kid. Paul's parents believed that Scott was their son and legally adopted him when he was 2 years old.
In 2012, DNA proved that the man that the Fronczaks had raised was not their biological son. The man is now 49 years old and resides in Nevada. As he got older, he suspected that he wasn't the Fronczaks' real child because he didn't resemble the rest of his family. Paul is of Polish and Croatian descent and the child the Fronczaks adopted has European and Jewish ancestry.
In light of this new information, the FBI has reopened the case and begun searching for Paul Fronczak. Chester and Dora are still alive and support their adoptive son's efforts to determine his true identity.
Paul is described as a Caucasian male with a height 1'8 and a weight of 9 pounds. He has brown hair & brown eyes. He was wrapped in a green & white checkered blanket when he went missing.
