== 2016 Sagamihara mass killings ==
At about 02:10 on 26 July 2016, Uematsu allegedly used a hammer to break into the care centre through a glass window on the first floor. He tied up a staff member, took their keys, and then went from room to room, stabbing the victims in their necks as they slept. Police were called to the care center by staff members at around 02:30 local time, reporting a man with a knife breaking into the building. However, Uematsu left the premises before being apprehended; he was recorded leaving the facility at 02:50 in security camera footage.

Armed police entered the building at around 03:00 where they discovered the crime scene. Twenty-nine ambulances were sent to the facility. Uematsu turned himself in at the Tsukui Police Station two hours after the incident with a bag containing kitchen knives and other bloodstained sharp tools. A knife was reportedly found in his car outside the police station. Marijuana was found in his system at the time of his arrest.

Uematsu allegedly killed ten women and nine men aged between 18 and 70 and injured 26 more, 13 severely.
