Investigators are still looking into what caused a deadly crash this morning that also left others injured.
It happened on I-75 in Madison County near the 93 mile-marker--that's between Richmond and Boonesboro.
Tire marks on the pavement and in the grass are still visible after an early morning crash that left one person dead and others injured. Police are still investigating exactly what caused the accident.
Four people were inside the van when it was hit from behind going northbound on I-75 near Richmond.
"It appears the van was traveling at a slow rate of speed, the semi truck did not see the van in the slow lane at which time they collided," says Trooper Robert Purdy.
One passenger was thrown from the van and killed. Two others were taken to the hospital with injuries. The driver of the semi truck and the fourth van passenger were both treated at the scene.
Police say unfortunately this area of the interstate is the scene of many accidents.
"We work a lot of wrecks for some reason between exit 95 and exit 90. It's a straight stretch of road, and apparently people aren't paying attention, that need to be," Purdy says.
They are looking closely at what might have caused this accident.
"At this time we're not sure what was the main contributing factor. We do not believe that drugs or alcohol had anything to do with it, however, there will be drug tests done," says Purdy.
While police continue investigating they are not releasing the name and age of the person killed in the crash. We're told the victim has a family member overseas who still needs to be notified.
The van carrying the four people had Michigan plates.
