Paul Fronczak triple disappearance

On April 27, 1964, a one-day old infant, Paul Joseph Fronczak was kidnapped from Michael Reese Hospital in Chicago, Illinois. A woman dressed as a nurse had entered the hospital room of Dora Fronczak and told her the doctor needed to examine the baby, and Dora handed the baby to the unknown woman, who left the hospital with the baby and never returned.

Two years later, the FBI told the baby's parents that they believed they may have found Paul in New Jersey. The parents met the New Jersey child and said it was their child, and the child was raised as Paul Fronczak. Paul Fronczak doubted his identity as both a child and an adult, and after taking a DNA test in 2012, discovered that he was not related to his raised parents, Dora and Chester Fronczak. In 2015, he was identified as Jack Rosenthal, who had disappeared in 1965. Additionally, he had a twin sister named Jill Rosenthal who also disappeared. The original 1964 kidnapping victim was found alive in Michigan in 2019, now named Kevin Ray Baty. Baty died from cancer in 2020.

The woman who kidnapped the baby has never been identified. Jill Rosenthal has never been located, but Paul Fronczak believes that their parents, Gilbert and Marie Rosenthal, may have killed Jill around the same time they abandoned him, as witnesses told Paul Fronczak that he and Jill had been abused as children. However, Fronczak and investigators believe there is still a solid possibility that Jill is still alive.

The 2021 documentary ''The Lost Sons'' showed Paul Fronczak exploring details of his case. Provided by Wikipedia
