One person was killed in a head-on collision in Kalamazoo early Sunday morning.

Police responded to the area of Kilgore Road and the Kilgore Service Road, shortly after midnight, where they found two vehicles with major damage. A passenger, in one of the vehicles, was found in full cardiac arrest, and officers immediately started life-saving measures. The victim was rushed to the hospital, but sadly, pronounced dead-on-arrival.

Drivers of both vehicles were transported to the hospital for non-life-threatening injuries. The investigation continues, however, alcohol is believed to be a factor in the crash.
