Authorities got involved after a relative of the deceased used Ancestry.com to put her family tree together.

A woman was getting information on Ancestry last year and her nephew Nathan Laskoski popped up. She saw he got married and he moved around the country, from Texas, to Mississippi, to Tennessee and eventually Pennsylvania.

But the problem is Laskoski died in 1972 when he was just two months old.

Authorities say 44-year-old Jon Vincent, back in 1996, escaped from a halfway house in Texas, went to a cemetery to find someone born around the same time he was.

Prosecutors say he picked Laskoski and found his birth certificate, which he used to get a social security number.

Authorities say that started 20-plus years of jobs, bank accounts, loans, marriage and divorce as Nathan Laskoski.
