Prosecutors demanded Tuesday that Tomohiro Kato be sent to the gallows for the 2008 massacre of seven people and wounding of 10 others in Tokyo's popular Akihabara electronics district.
In their closing argument, the prosecutors told the Tokyo District Court that Kato, 28, is mentally fit to be held liable for his "extremely self-centered, premeditated" crimes.
"In a matter of minutes, seven precious lives were lost, and 10 people were wounded. Among indiscriminate random murders, this attack had a large casualty count and was one of the most heinous crimes ever committed," they said.
