On the night of February 20, 2016, a spree shooting took place at an apartment complex, a Kia car dealership, and outside a Cracker Barrel restaurant in Kalamazoo County, Michigan. Six people were killed, and two others were injured. Police detained a 45-year-old Uber driver, Jason Brian Dalton, in the shootings. He was subsequently charged with murder, assault, and criminal firearm use two days after the shootings. After he was found competent to stand trial, Dalton's lawyers planned a legal insanity defense for their client.
