A 17-year-old suspected of fatally stabbing a woman in Toyokawa, Aichi Prefecture, accompanied police in retracing the route by which he is thought to have fled the murder scene.
The youth, a third-year student at a private high school in the prefecture, is suspected of killing Kiyo Tsutsui, 64, at her home on the evening of May 1, and slashing her husband, Hiroshi, 67, across the neck when he returned home and found them.
Investigators and the suspect left Toyokawa Police Station at around 9:30 a.m. to confirm the route the youth allegedly took to get to Nagoya Railroad Co.'s Ko Station from Tsutsui's house.
In the afternoon, they were to re-enact the killing at the victim's house after inspecting the scene of the murder, police said.
The boy was arrested May 2 after he turned himself in at a police station in front of JR Nagoya Station in the evening. He reportedly told police that after stabbing Kiyo to death, he changed clothes in a nearby bamboo grove, rode his bicycle to Ko Station and fled by train.
The youth told police that he wanted to "experience killing people," and had entered Tsutsui's house because the "front door was slightly ajar," according to police sources.
The sources also quoted him as saying that he murdered an elderly person because he "thought it wrong to target young people with a future."
The boy spent the night of May 1 in a public lavatory and traveled between Gifu and Nagoya by train before turning himself in, they said.
