During questioning, Sato, who has been accused of attempted murder, admitted to stabbing Arashi. “About a week ago, I started to become troubled about whether I would stab [him],” Sato was quoted. “So I had him drink some wine I laced with a sleeping powder. Once he was asleep, I stabbed him.”

In addition to considering changing the charges to murder, police are examining the contents of glass found to contain liquid that was inside the residence.
