(Sioux Falls, SD) — Mental illness is being deemed a factor in South Dakota’s most recent officer-involved shooting. Authorities say a man was carrying knives and approaching officers when he was shot in Sioux Falls last Thursday. It happened at Southeastern’s Cayman Court Assisted Living Facility, a location for people “with severe mental illness.” State Attorney General Marty Jackley said over the weekend that law enforcement went to serve a warrant for a mental illness hold, but the situation escalated after an extended period of discussions. Thursday’s officer-involved shooting is still under review by South Dakota’s Division of Criminal Investigation.
