GIFU – Police have found a stick that a teen apparently used to beat his 13-year-old girlfriend in a vacant building in Nakatsugawa, Gifu Prefecture, before strangling her, investigators said Sunday.
Other sticks and some cloth were found in a room on the third floor of the former pachinko parlor, leading police to suspect the 15-year-old boy, who was arrested late Friday, used them to kill Nao Shimizu.
They suspect the boy may have known that the cloth and sticks were in the room before he killed her, investigative sources said.
The boy is a first-year high school student. His name is being withheld because he is a minor. Police sent him to prosecutors Sunday on suspicion of murder.
According to investigations, he used a strip of cloth to choke Shimizu, a second-year junior high school student, after beating her in the head at around 6:30 p.m. Wednesday.
Police said Sunday an autopsy showed the cause of death was strangulation.
The boy was quoted as telling police, “I did it alone,” and, “I intended to kill her.”
Keiichi Ozeki, a lawyer who met the boy in detainment at a police station Saturday, said the teen shed tears and said, “I did an unforgivable thing.”
Ozeki quoted the boy as saying he and the girl got together at the building after he arranged a meeting by telephone.
He said the teen told him that the purpose of the rendezvous was to give her some school clothes after he had graduated from the same junior high last month, and denied calling her to the site with an intent to murder her.
Police said they believe the two had been going out for two or three years.
They searched the boy’s home and several other locations Saturday. Acting on information from the boy, they found the victim’s cell phone hidden in a drawer in the pachinko parlor.
