Indiana State Police said Thursday that Richard Wayne Landers Jr. was abducted in July 1994 during court proceedings over his custody in Wolcottville.
Police say a 24-year-old man with the same Social Security number and birth date as Landers but living under a different name was located in October in Long Prairie, Minn.
His grandparents also were living under aliases nearby and confirmed his identity.
The grandparents were initially charged with custody interference, but charges were dropped in 2008 after the case went cold.
Police spokesman Sgt. Ron Galaviz says Landers' father was never in the picture.
Galaviz says an attorney is working with Landers' mother to reconnect her with her son.
