SAGA — A 24-year-old Vietnamese male technical intern trainee has been arrested in relation to a murder-robbery and trespassing case in Imari, Saga Prefecture, according to the Saga prefectural police.

Suspect Dam Duy Khang is alleged to have entered the residence of Maiko Mukumoto, a 40-year-old Japanese language instructor, around 4:20 p.m. on Saturday, the police said. It is believed he threatened her with a knife and stole ¥11,000 before killing her by slashing her neck as she resisted.

An autopsy determined that Mukumoto died from blood loss, with multiple stab and cut wounds on her neck and abdomen.

According to the prefectural police, Mukumoto and her mother, who is in her 70s, opened the front door after the intercom rang, and the man entered. The man was quoted as telling the two women at the entrance, “Money” and “Show me your wallet.” He is suspected of stabbing them both.

The mother fled and asked a neighbor to call the police. When officers arrived, they found Mukumoto lying unconscious in the entranceway, and she was later confirmed dead. The mother suffered a cut to her neck, but her condition is not life-threatening.
