A suspect who was arrested in a case through which 4 folks have been killed in Nakano, Nagano Prefecture, mentioned that he thought the 2 ladies have been making enjoyable of him whereas they have been taking a stroll. I do know that.
The police imagine that he might have attacked him as a result of he thought he was swearing, and are investigating when and why he began to carry a grudge.
