Terre Haute’s Tribune-Star reports that the tractor-trailer was traveling east on Interstate 70 west of Terre Haute when traffic in the eastbound lanes started to slow because of an active fire, reportedly from a tractor-trailer brake fire, along the highway.
Just before 5 p.m., the tractor-trailer failed to slow down and slammed into the back of a Toyota car, pushing it into the back of a flatbed trailer and causing it to burst into flames. The three occupants of the car died at the scene.
Authorities said that after the tractor-trailer hit the car, it slammed into the back of a Maverick flatbed truck hauling steel bars, which impaled the tractor-trailer and killed the driver. The Associated Press and several other sources report that the driver of the tractor-trailer was identified as Jeffrey D. Kolkman, 38, of Jenison, Michigan.
The occupants of the car were identified as:
- Brian E. Lee, 48, of West Terre Haute, the driver of the Toyota
- Mr. Lee’s son, Aaron, who was sitting in the front passenger seat
- Stephanie Swaim, 45, of Brazil, Indiana, who was sitting in the back seat
Indiana State Police continue to investigate the crash, with a focus on what factors could have caused Mr. Kolkman to fail to adjust his speed.
