What kind of person is Sasaki, who is believed to be the mastermind behind the crime? A nearby resident shared their impressions:

“Sasaki and his family moved here about two years ago. I had the impression of him being a good father, playing catch with his child in front of the house or letting them play in the inflatable pool during the summer.”
