There are reports that the suspect, Ando, struck Yuki-kun. Residents near the school and parents of children in the same class have testified to this. Whenever Yuki-kun’s adoptive father was mentioned, he would suddenly become somber and strongly refuse to talk about “Dad.” It seems that the suspect may have struck Yuki-kun, and since then, the very word “Dad” may have become unpleasant to him. However, the police have not yet officially released any evidence substantiating violence. But since multiple accounts from local residents align, investigators appear to be examining this aspect very carefully.
