SHIZUOKA – Police arrested a 56-year-old woman on Sunday for allegedly stabbing her husband and daughter to death and injuring two other family members in a domestic dispute, police said.
Police arrested Miyoko Komiyama on suspicion of stabbing her husband, Shigemitsu, 59, and their daughter Reiko, 25, to death with a knife around 5:30 a.m. at their home in Nagaizumi, Shizuoka Prefecture.
She also stabbed her pregnant 28-year-old daughter, Takako Ushirokawa, and Takako’s husband, Kazunori, 32, from Yokohama, police said. Takako was rushed to hospital and gave birth to a baby boy, one day ahead of her due date.
According to investigators, Takako Ushirokawa called for an ambulance at around 5:30 a.m. Sunday, reporting that her family members had been stabbed.
When ambulance workers arrived at the family’s residence, Shigemitsu and Reiko had already died from stab wounds to their faces and necks, police said.
The Ushirokawa couple, who live in Yokohama’s Kanazawa Ward, suffered stab wounds to their wrists and elsewhere. Police immediately arrested Miyoko on suspicion of murder and attempted murder, and she admitted to the charges, they said.
After stabbing the four, Miyoko cut her neck and left wrist in a suicide attempt, leaving a wrist injury that may take 10 days to heal, they said.
Takako, who was visiting her parents’ home in anticipation of giving birth, was brought to a nearby hospital after she was stabbed, and the baby was safely born.
According to police, Miyoko visited the local police station in early August saying that her husband was having an extramarital affair and that she wanted advice on what to do about their assets. However, police said that she did not identify herself at the time.
She was advised to discuss the issue with her husband through her relatives.
The site of the incident is a quiet residential area about 3 km northwest of JR Mishima Station.
