Column: Murder case in Saikai, Nagasaki Prefecture attributable to problems involving violence between a man and a woman, and the series of police responses to this incident

## (1) Case Overview

From October 2011, Chiba, Nagasaki and Mie Prefectural Police were consulted regarding problems involving violence between a man and a woman, by the victim’s father and others. In December of the same year, the man involved in said trouble forced his way into the woman’s family home in Saikai, Nagasaki Prefecture, and murdered the family.

(2) Issues concerning Police Response and Preventive Measures against Recurrence

The officer who handled the previous examination was also included in the scope of the re-examination. Furthermore, the NPSC also issued a request to the Chiba PPSC for a thorough inspection of the investigation.

For the re-examination, the Chiba PPSC convened a total of seven meetings, including extraordinary meetings, and conducted their inspection while demanding continual reports on investigation status, etc. The results of the re-examination revealed that the recreational excursion was considered to have affected the
