The convenience store is where Mr. B works, and the sprinklers were activated at the time, so the fire did not spread into a major fire. It is known that Mr. A used a weapon purchased in advance as a crime tool and set the fire by spraying a previously prepared flammable substance into the convenience store.
Even though they were divorced, it was revealed that he sexually assaulted Mr. B by repeatedly using words and actions to put psychological pressure on Mr. B and continuously threatened to reveal personal secrets.
Accordingly, Mr. B reported it to the police, and although Mr. A was ordered by the court to refrain from approaching, it was found that he went to the place where Mr. B worked and killed him for reporting him.
Mr. A denied charges such as sexual assault and quasi-rape, saying, “There is no conclusive evidence on the part of Mr. B regarding the rape charge, and he consented to it in advance.” He admitted to charges of revenge murder and arson.
