The BBC reports once more:

A teenage Japanese boy has walked into a police station carrying a severed human head and claiming to have killed his mother.

The 17-year-old went to a police station in the town of Aizuwakamatsu, north of Tokyo, carrying the head in a sports bag, Japanese media said.

Uh… well, just mildly gruesome, but it’s particularily strange that he would carry around the head. Couldn’t he just have called the police?
