For the sake of clarity and because I think this latest news will attract new posters, I'm summarising the basics of the case and am referring to the two men involved as Bio Paul and Paul Jack - all will become clear, hopefully!
In 1964 newborn baby Paul Froczak was kidnapped from hospital by a bogus nurse, never to be seen again.
In 1965 a toddler was found in the street and, with the absence of DNA testing, it was eventually decided he must be Paul and in 1966 he was returned to the Fronczak family. He grew up knowing about the kidnapping as he found newspaper clippings about it.
As an adult Paul was suspicious he might not be "Bio Paul" and genetic testing confirmed this. So who was he really? And where was Bio Paul?
A few years ago it was discovered that Paul was actually a boy named Jack Rosenthal who had disappeared as a young child. Jack had a twin sister called Jill who disappeared at the same time and is still missing. The Rosenthal family was tracked down and Paul was reunited with them, though their identity has been kept a bit hush hush... the family was a bit of a mess by all accounts and the circumstances about the twin's disappearance is patchy.
Paul (from now on we'll call him Paul Jack) remains loyal to his adopted Fronczak family while getting to know the Rosenthal side of his family.
Fast forward to now and it seems "BIO PAUL" HAS BEEN FOUND! He is a 55 year old from Michigan and has been made aware of his true identity. More info to come this week.

Hope I got all that right, I've kept it as basic as possible as it's very confusing. Shout if I missed anything crucial.
