All I can really say here is “Jesus Christ.” No, really. This is pretty damn heinous.

Earlier today, the Tokyo Metropolitan Police Department arrested Jung-hyun Park on homicide charges. Park, age 41, allegedly murdered his 38 year-old wife at their home last year.

According to the Criminal Investigation Division, Park strangled his wife, Kanako, in the early hours of August 9, 2016 at their Sendagi resident in Tokyo’s Bunkyō ward. He called emergency services at about 2:45AM. In the call, Park explained that his wife collapsed at the bottom of the stairs, near the entrance of their home’s first floor.

While she was rushed to the hospital, Kanako was pronounced dead on arrival. When asked by police, Park changed his explanation, stating that his wife committed suicide.

An autopsy on the body was performed, which turned up evidence that the cause of death was strangulation. According to the police report, nearby security cameras confirmed that nobody had entered the residence prior to the time of death.

The entire family, including Park’s four children, were home at the time of the incident.

Jung-hyun Park was the is the assistant editor-in-chief of Kodansha’s Morning magazine. He was also the first editor for Hajime Isayama’s Attack on Titan manga series.

Kodansha issued a statement regarding the case. The publisher states that “[Mr. Park] maintains his innocence. We are awaiting the results of the investigation, and are dealing with [the incident] with utmost discretion.”
