Fukushima teen went to karaoke after killing mother

An arrested 17-year-old boy has told police he went to a karaoke shop after killing his mother last week at an apartment in Fukushima Prefecture, investigative sources said Sunday. Police are examining security-camera images provided by the karaoke shop to uncover his behavior before he turned himself in with the mother's severed head after the suspected murder in the city of Aizuwakamatsu, the sources said.

According to investigations so far, the teen is suspected of killing his mother with a knife around 1:30 a.m. last Tuesday and cutting her head and right arm with a saw. He is then believed to have changed his clothing, gone to the karaoke shop on a bicycle, moved to an Internet cafe and stayed there mainly listening music DVDs for about two hours from around 5 a.m. that day before going to the police station by taxi. He is believed to have carried the severed head in a school shoulder bag the whole time.
