WARREN COUNTY, Mo. — A 55-year-old man was chasing a dog when a car fatally struck him along westbound I-70 in Warren County Thursday night, according to authorities.

The Missouri Highway Patrol identified the victim as David S. Courtway, of Union. He went onto the highway, attempting to catch the dog moments before a 2015 Honda Civic hit him around 9:30 p.m.

A 22-year-old woman driving the vehicle slammed on the brakes but couldn’t stop in time. The car veered off the interstate after the crash.

Courtway was pronounced dead at the scene. The driver was treated for minor injuries at a hospital.
