Twenty-Five Year Old Japanese Man Arrested After Massacre:

TOKYO -- A lone attacker rammed a truck into pedestrians, then slashed his way with a survival knife through Sunday shopping crowds in one of Tokyo's most popular neighborhoods, killing seven people and wounding 10.

Police quoted Tomohiro Kato, 25, as saying he came to the Akihabara district, a canyon of computer and electronics stores, vowing to "kill people."

"I am tired of the world," the part-time worker in an auto parts plant reportedly told police after his arrest. "Anyone was OK."

Kato reportedly drove a rented 2-ton truck from his hometown of Susono, about 60 miles southwest of Tokyo, arriving in Akihabara around noon. The area, renowned as the center of Japan's anime and manga culture, is particularly clogged with shoppers on Sundays when its streets are closed to vehicles for "Pedestrian Paradise Day."

The assailant plowed the truck through a major intersection, knocking down at least three people before striking a taxi and stopping. Witnesses said the attacker then fled the damaged vehicle, furiously stabbing one of the injured pedestrians and a policeman who came to the aid of the victims.

He then bolted down a side street, stabbing others as he went and triggering confusion as thousands of shoppers surged to either escape the rampage or to get a closer look. Television footage showed the intersection littered with sneakers and bloody clothing.

The dead were six men ages 19 to 74 and a 21-year-old woman. A policeman ended the frenzy by knocking the knife from the attacker's hands with a nightstick. But the assailant did not surrender until the officer drew his gun. Video posted on Japanese websites showed a man identified as Kato, wearing a black T-shirt under a white suit and bleeding slightly from a head wound, with his hands raised. It then showed the policeman pushing him into a fetal position against a wall and sitting on his legs while using his radio to call for help.

So many disturbing details in those few paragraphs. Kato isn't the first freak to blog about a massacre and he won't be the last.
