In addition to a head injury that seems to be the cause of death for a boy, three mothers were re-arrested on suspicion of being fatally injured for assaulting and killing a 5-year-old boy in a house in Honjo City, Saitama Prefecture. The police are investigating the details, as he did not see any scars that seemed to have been assaulted in the past.
Chika Kakimoto (30), an unemployed Hiroki Niwa (34), and Yoko Ishii (54), an unemployed wife of Niwa's inner relatives, are about January 18th. He was re-arrested on the 26th on suspicion of being fatally injured, alleging that Kakimoto's eldest son, Ayumu-kun (5 years old), was killed by assaulting him on the floor in a house in the city where he lived.
According to the police, Ayumu-kun is believed to have died by hitting his back of the head when he was thrown to the floor multiple times due to the condition of his body.
On the other hand, there were no old scars that had been assaulted in the past, other than the head wound that was thought to be the cause of death.
Ayumu suddenly stopped attending the nursery school on January 12, six days before his death, and police are investigating the details of this period.
