(CNN) — A 49-year-old Nevada man grew up believing he was kidnapped from the hospital as a day-old baby and was returned at age 2 to his parents in Chicago, months after being found abandoned in a stroller in New Jersey.

The FBI closed the case: The toddler looked like the missing newborn.

The audacious kidnapping — by a woman dressing as nurse who told the mother to hand over her infant because the doctor needed to examine him — was a sensational crime nearly a half-century ago.

But now the life of Paul Joseph Fronczak has taken another an extraordinary turn, he told CNN affiliate KLAS.

After taking a home DNA test, Fronczak said, he discovered he wasn’t the missing baby.

The FBI has reopened the case to tackle the questions of what happened to the real kidnapped baby and who Fronczak is, exactly, he told KLAS.

“I don’t know how old I am, or who I am, or what nationality, all those things you just take for granted,” he said. “The FBI decided that because my ears matched the Fronczak baby that I was probably the Fronczak baby.”

He told the Las Vegas station the furor surrounding the 1964 investigation “was huge.”

“My parents had letters from the pope, letters from people all over the country. It was a huge case,” he said. “My parents got really frustrated because they had reporters hanging outside their windows, climbing telephone poles, taking pictures of them at church, following them all over the place.”

Fronczak, who lives in Henderson, Nevada, with his wife, Michelle, and daughter, Emma, said his name was Scott McKinley when he was found abandoned in 1965 at age 14 months.

The people who became his parents, Dora and Chester Fronczak of the Chicago area, were able to take possession of him in June 1966 under the belief that the boy was indeed their child, KLAS reported. The Fronczaks adopted and renamed the boy, taking him into their Chicago home.

But as he grew older, Fronczak developed a hunch he didn’t fit into the family. He didn’t look like his Polish and Croatian parents, who didn’t reveal much about the kidnapping, he said.

Last year, Fronczak bought a home DNA kit and took a swabbing from his parents while they were visiting from Chicago. A week later, the results of the test ruled out his being the biological son of Dora and Chester Fronczak, he said.

The DNA technician told him that “there is no remote way that you are the Fronczaks’ baby,” he said. “I thought, ‘Wow.'”

He revealed his story to KLAS just before what was supposed to be his 49th birthday in April. At the time, he said, he didn’t even tell his adoptive parents what he learned because it was too agonizing.

The Chicago office of the FBI is now investigating the dual mystery of the kidnapped Fronczak baby and the abandoned Scott McKinley, with assistance from the agency’s Las Vegas office, the TV station said. The original kidnapper in the Fronczak case was never found.

Neither Fronczak nor the FBI returned CNN’s calls for comment Thursday.

Since obtaining the DNA findings, Fronczak submitted the results to Ancestry.com, a genealogy tracing company. Based on his DNA, Fronczak is discovering blood relatives: he’s found a third cousin, KLAS reported.
