According to the police, at around 5 pm on 29 July, a mother in her 20s reported that her child was lying limp in the parking lot of Bosai No Oka Park in Atsugi City.
Two children in the car were taken to the hospital, presumed to be suffering from heat stroke, but the younger brother, a one-year-old boy, died.
The older sister, a two-year-old girl, who was also in critical condition, died at 4 am on 2 August.
When interviewed by the police, the mother said: "I let my children go to the park to play, but when I got to the park my children were sleeping, so I sat in the car with them for about 30 minutes, without turning on the air conditioner. I only open the window and constantly play with the phone, and then the most unfortunate consequences happen."
