Investigators only recently learned Adam Herrman disappeared in 1999 and are focused on finding him. Adam was 11 when he disappeared from a mobile home park in Towanda, where he lived with his adoptive parents.
Irvin Groeninger II is the boy’s biological father. The Indiana truck driver says he last saw his son when the boy was 18 months old.
He was divorced when the child was removed from the biological mother’s home because of alleged abuse. He says he was cleared of any wrongdoing and tried to get the boy back.
Groeninger says he wants his son to know he loves him and wishes he had fought harder to get custody of him
