NEWS BRIEF At 2:10 a.m. Tuesday morning, 26-year-old Satoshi Uematsu broke through a window of a facility for the disabled in Sagamihara, Japan, and went on a stabbing rampage that killed 19 of the 150 patients in the facility, wounding 25 others. Among those killed were 10 women and nine men, ranging from 19 to 70 years old, according to the Associated Press.
Less than an hour later, Uematsu turned himself into police. The attack is the deadliest mass killing Japan has seen in decades.
The facility, Tsukui Yamayuri-en, was not unfamiliar to Uematsu. He began working there in 2012, and reportedly held a grudge against the facility for firing him last February. According to Kanagawa prefecture officials, the facility employs more than 200 people, though only nine of them were working on the night of the attack—a staffing shortage that Uematsu would have foreseen, according to Japanese media.
Though little is known of Uematsu’s background, the Japanese Parliament office told the AP that he attempted to deliver a letter to a local legislator in February, outlining his intentions of committing an attack on two facilities. In the letter, he called for “a revolution,” demanding that all disabled people be put to death through “a world that allows for mercy killings.” He further demanded that he be declared innocent on the grounds of insanity, given 500 million yen ($5 million) in aid, and receive plastic surgery.
