Paul Fronczak triple disappearance

Fronczak then wanted to find out his true identity, and also wanted to find out what happened to baby Paul. A group of genealogist volunteers called the DNA Detectives offered to take up his case free of charge in 2013. On June 3, 2015, the group told Fronczak that they had identified him as Jack Rosenthal of Atlantic City, New Jersey, who had seemingly vanished in 1965. They informed him that he also had a twin sister who had disappeared named Jill. Fronczak later met biological relatives, some of whom informed him that they had seen him and Jill as children, and suddenly stopped seeing them, and that his biological parents, Gilbert and Marie Rosenthal would come up with excuses as to why the twins would no longer be there at family meetings. Biological family members also recalled that they had seen Jack and Jill badly abused and neglected, and one family member said they witnessed Jack and Jill sitting "in a cage". Gilbert was described as "an angry man" after returning from the Korean War with PTSD, and Marie was described as a heavy alcoholic. Susan Wohlert, who had babysat the Rosenthals' older children, later told Fronczak that when she had babysat, Gilbert and Marie Rosenthal had told her "not to bother" with the twins upstairs. She went upstairs out of curiosity, where she found Jack and Jill in a room which was empty besides them in their cribs. She said that Jack had a black eye, that he and Jill were dirty, and that the room reeked of urine because their sheets had not been changed. She spent the whole night with Jack and Jill, and Gilbert and Marie were furious the next morning when they found her in Jack and Jill's room. Wohlert stated that she got the impression that Gilbert and Marie had been partying and that they smelled like alcohol. Gilbert and Marie both died in the 1990s from cancer.

Fronczak said that he believes Jill may have been killed or "something tragic" may have happened to her, and that his parents then decided to get rid of him because "they couldn't explain just one twin". He said, however, that he believes Jill could still be alive, and the National Center for Missing & Exploited Children created a composite reconstruction image of what Jill may look like if she is still alive. No pictures of Jill as a child are known to exist. The investigation into her disappearance is ongoing.[1][5][6][7]

In 2019, a Michigan man named Kevin Ray Baty was identified as the baby Paul Fronczak who had been kidnapped from a Chicago hospital in 1964, though his identity was not revealed to the public until 2020, when Ray died of cancer on his 56th birthday. Before his death, he spoke multiple times on the phone with his biological mother, Dora Fronczak, but they were never able to meet in person. Baty had been raised by Lorraine Fountain, who had been dating a doctor from Chicago when she suddenly moved to Arkansas for a year and then returned with baby Paul, who was raised as Kevin Baty. Fountain died in 2004. It is unclear how Kevin got the last name Baty. The perpetrator of his kidnapping has not been identified to this day. The FBI investigation into the kidnapping remains open.[5][2][8][9]
