CLAY COUNTY — An Indianapolis man died Saturday morning in a wrong-way crash on Interstate 70 in Clay County, and an Indiana State Police trooper suffered injuries when his cruiser was struck by a motorist's vehicle during the investigation.

John D. Slack, 72, of Indianapolis, was driving the wrong way in the eastbound lanes of I-70 near the 22 mile marker at 6:05 a.m. Saturday when he collided with a semi-truck driven by a 21-year-old Ontario, Canada man, according to a news release from Indiana State Police.

State police said the truck driver was traveling eastbound in the passing lane alongside another semi-truck when he saw Slack's 2019 BMW driving toward him. The truck driver attempted to avoid the collision, but state police said was unable.

Slack was pronounced dead at the scene, while the truck driver and his co-driver were not injured.

During the investigation into the crash just after 9:15 a.m., Indiana State Police Trooper Troy Cobb was injured when a motorist, Holly J. Hedden, 21, of Terre Haute, collided with his cruiser while driving a 2006 Buick.

Cobb is resting at home after he was treated and released from Terre Haute Regional Hospital, state police said. Hedden was not injured in the crash.

Cobb, who was inside his police vehicle with its emergency lights activated, was assisting with traffic direction during the investigation into the wrong-way crash.

State police said neither drugs nor alcohol were contributing factors in either crash.
