The man arrested for the murders, Gota Tsutsui, 27, from Kuwana in Mie Prefecture, was already under investigation by Chiba police for allegedly assaulting the daughter of one of his victims. According to NTV, he had been warned twice by police and was already under investigation for allegedly assaulting Yamashita's 23-year-old daughter. (Japan Today)
