JOHNSON COUNTY, Ind. — It happened around 8 p.m. on Interstate 65 near Edinburgh.
Witnesses told police they saw dangerous driving turn deadly.
They say someone in a white Chevy Cobalt was speeding, weaving in and out of traffic, gesturing toward other drivers and suddenly braking in front of them.
"This white Chevy Cobalt cut me off and I had to slam on my brakes," Andrew Hiester of Seymour, who witnessed the crash, said. The white car zipped in between two semis and a gold truck locked its brakes, which sent his pickup truck airborne, landing into the woods upside down. The driver was ejected.
Hiester was one of several witnesses who stopped and gave the injured driver CPR.
"If somebody needs help I'll go and help them," Hiester said of his actions. "It's just one of those things that's been instilled."
"We have so many good-hearted people out there who will see someone and stop and put themselves at risk to offer that help and that's exactly what happened last night," said Indiana State Police Sgt. John Perrine.
Despite their efforts, 72-year-old Mark Raub of Nashville, Indiana died at the scene.
Witnesses said a loved one driving behind Raub watched the whole thing.
The white Chevy Cobalt never stopped.
Police are asking for the public's help, hoping a second set of eyes, or several in the form of dashcams, captured the crash or the car on the highway.
"Either look at that dash cam yourself, or let us know," Sgt. Perrine said. "Maybe somebody 10 miles in either direction passed this car or the car passed them."
Both police and those who tried desperately to save the victim desperately want justice.
"It was gut-wrenching," Hiester said. "He died in our hands, and it's like I know I did everything and gave everything I could have. But it's still one of those... what could I have done to make this innocent man who did nothing wrong still have a life today?"
Investigators tell 13News they have heard from a trucking company that had dash cams on three trucks in the area Tuesday.
They're reviewing the footage.
People who have a dashcam video and were on I-65 between 7:45 and 8:45 that evening, or witnessed something that can help investigators, are asked to call Indiana State Police at 317-899-8577.
