Police in Tokyo on Thursday arrested a 75-year-old man on suspicion of killing his 85-year-old common-law wife. Police said the suspect, Seigo Arai, has admitted to the charge and quoted him as saying he was worn out from looking after the woman who had Alzheimer's disease.
Police said Arai strangled Hinako Toyama with a necktie around 10 p.m. on Tuesday night on a bench in a park near their home in Kita Ward.
Arai went to a nearby koban (police box) at around 1 a.m. Thursday and told police he had strangled his wife in the park.
The couple lived with their son who is in his 50s. He found a note from his father when he came home at 10 p.m., in which his father said he was exhausted from being a caregiver.© Japan Today
