ABC News' Barbara Walters and Brian Ross Investigate the Mystery of a Baby Stolen Almost 50 Years Ago

Walters Speaks to the Man at the Center of the Case, Paul Fronczak, in an Exclusive Interview to Air on "World News" and "GMA"

Who is Paul Fronczak? Paul Fronczak was, until recently, believed to be the baby stolen from a Chicago hospital nearly 50 years ago. The intriguing case made headlines earlier this year when Paul, after years of uncertainty, took a DNA test that proved he is not the real Paul Fronzcak. Just this week, the FBI has reopened the case of the stolen Chicago baby.

"20/20? and the ABC News Investigative Team, led by Barbara Walters and Chief Investigative Correspondent Brian Ross, have been following Paul's story for months. ABC cameras are there as he searches to uncover his true biological identity. Portions of Barbara Walters' exclusive interview with Paul Fronczak will air tonight on "World News with Diane Sawyer" (6:30 - 7:00 p.m. ET) and tomorrow morning on "Good Morning America" (7:00 - 9:00 a.m. ET), as well on abcnews.com, ABCNewsOne and ABC News Radio. " Stolen at Birth: A 20/20 Investigation" will air on ABC in the fall.
