The suspect in Saturday's deadly shooting rampage in Kalamazoo, Mich. visited a gun shop and bought a tactical jacket hours before the attack, authorities said.

Kalamazoo Police Chief Jeff Hadley also said Tuesday that 45-year-old Jason Dalton had no history of mental illness and wasn't prescribed any medication that would have prevented him from owning the weapon he allegedly used to kill six people and injure two others.

Dalton is charged with murder and attempted murder in the shootings, which took place outside an apartment building, a restaurant and a car dealership over a span of almost seven hours. Authorities said Dalton paused between shootings to make money as an Uber driver.

"He was a law-abiding citizen up until he pulled the trigger on the first victim," Jonathan Southwick, owner of the gun store Dalton visited in Plainwell, 20 miles north of Kalamazoo. "There are no laws you could put into place to stop what had happened."
