The man arrested for allegedly killing 19 people in a care home had contacted government officials about changing the law to allow for euthanasia and volunteered to do the killing himself.

"As to my goal, with the daily lives of persons with multiple disabilities being extremely difficult in the home, I would like a world where (a disabled person) can be euthanized with the consent of a guardian," read part of the letter written by 26-year old Satoshi Uematsu.  For sending his hideous intent in a note to the Deputy Prime Minister, 26-year old Satoshi Uematsu was "involuntarily hospitalized" earlier this year.  He was also separated from his job at the Tsukui Yamayuri-en facility in Sagamihara, a town southwest of Tokyo in Kanagawa Prefecture.  Tsukui Yamayuri-en sits on a wooded bank to the Sagami River, and provides care for people with a wide range of disabilities.  It's close to the home of the killer.

Police say Uematsu returned to Tsukui Yamayuri-en at 2:30 this morning.  Dressed in black, he managed to gain entry to the facility and proceeded to stab dozens of profoundly disabled people in their sleep.  Asahi Shimbum reports that of those killed, ten were women aged 19 to 70; nine men aged 41 through 67 also perished.  Another 26 people are injured, 20 of them seriously.

"They are truly innocent people,"said another former worker at the facility.  "What did they do?  This is shocking." she told Japanese television station TBS

At 3:00 AM, Uematsu turned himself in to police and reportedly confessed.

For Japan, it stirs up memories of other mass stabbings.  Eight children were stabbed to death at their school in Osaka by a former janitor in 2001.  Seven people died in 2008 when a man drove a vehicle into a crowd and began stabbing people in Tokyo's popular electronics and "anime" district of Akihabara.  It's also likely the worst mass killing since the end of World War II.
