A 21-year-old Fairborn man was killed on I-675 when he got out of his truck after he hit a concrete wall.
Troopers identified the victim as 21-year-old Chay Demint.
They said Demint crashed his truck on the left side of the road.
Then, a passerby stopped on the right side of the road and yelled to Demint to get off the highway.
That is when another truck drove through and hit Demint, troopers said.
The driver of that second truck was taken to the hospital, but troopers said that person's injuries are not considered life-threatening.
The crash happened around 11:45 p.m. where Spangler Road turns into I-675 and goes over I-70.
The highway was shut down for about five hours while crews were on the scene.
