There is a suspicion that a 26-year-old man in Saitama Prefecture, who was arrested in the case of the murder of four family members in a house in Sakai Town, Ibaraki Prefecture in 2019, saved an image of the area around the scene and then deleted it. I found out by interviewing the investigators.
Police are investigating the suspicion that they had confirmed the situation around the scene in advance.
In September 2019, an office worker Mitsunori Kobayashi (48 at the time) and his wife Miwa (50 at the time) were stabbed and killed in a house in Sakai Town, Ibaraki Prefecture, and the eldest son of a junior high school student and the second daughter of an elementary school student were seriously injured. On the 7th, police arrested an unemployed Yusei Okaba (26) living in Saitama prefecture on suspicion of murdering a couple.
According to the investigation so far, no contact has been found with Mr. Kobayashi's family, but it is suspected that Okaba saved an image of the area around the site and then deleted it. I found out by interviewing.
As a result of analyzing the items seized in the search at home etc., the deleted image could be restored.
According to the investigation so far, it is known that the tear spray was purchased on the Internet before the incident, and the police suspected that they had confirmed the situation around the scene in advance, and are investigating the situation.
Police have not disclosed their approval or disapproval.
