IONIA, MI — Authorities have identified the two men involved in Wednesday night's double-fatal shooting that police believe was spurred by road rage.

Ionia residents James Pullum, 43, and Robert Taylor, 56, were pronounced dead at Sparrow Ionia Hospital soon after they engaged in a shootout with each other, according to the Ionia Department of Public Safety.

Police responded to reports of shots fired just before 7 p.m. at Wonder Wand Car Wash in the 400 block of South Steele Street.

An initial police investigation showed the men turned into the car wash's parking lot after a road rage incident, authorities said. They reportedly exited their vehicles, drew handguns and exchanged fire.

The men were discovered by police at the scene with gunshot wounds.

They both held permits to carry concealed weapons.

The Ionia County Sheriff's Department and the Michigan State Police Crime Lab currently are investigating the case.

A call seeking additional information from the Ionia Department of Public Safety officials has not been returned, but an employee said additional information is expected to be released in the coming hours.
