Yūki Adachi joined the search for his missing son in Kyoto.
Sources say the adoptive father may have killed the boy and left the body near their home rather than in the mountains where it was ultimately found.
He possibly tried to delay the discovery of the remains during the search operation. This follows the father's earlier arrest on body-abandonment charges and admission to choking his son.
