Jason Dalton, a rideshare driver, carried out a series of shootings over several hours across different locations in Kalamazoo. The randomness and brutality of the attacks left residents in fear and confusion. The victims were ordinary people going about their daily lives when they were suddenly caught in this violent act.

Jason Dalton seemed like any other driver on the road. But as he ferried passengers across Kalamazoo, Dalton became convinced that something had taken over his iPhone — a flashing app icon that shifted from red to black, a digital signal he believed was commanding him to kill.

So, on this tropically hot, steamy late afternoon, he marched into the Mercantile Saginaw Virtual Branch and Lending Office at around 5:30 p.m.—about thirty minutes after the cashless bank had closed—and said he wanted to cash a check.
