MARIETTA, Ga. - Police are searching for the driver of a pickup truck who struck and killed a tractor-trailer driver early Wednesday morning on Interstate 75, shutting down multiple lanes for hours.
Crash along I-75 at South Marietta Parkway
What we know:
Investigators say the crash happened around 2:30 a.m. near the South Marietta Parkway exit.
Two tractor trailers sideswiped each other while heading north, and both drivers pulled over, one stopping on the interstate and the other on the exit ramp.
Police say the drivers got out to exchange information when another vehicle struck one of them, 36-year-old Terrell Lowdermilk of Chattanooga, who was standing in the left lane of the entrance ramp. He died at the scene.
"Both drivers trying to do the right thing got out of their vehicles and attempted to make contact with each other. It’s at that moment that now tragedy occurs," said Marietta police Officer Chuck McPhilamy.
Multiple lanes of I-75 northbound remained closed for several hours while crews cleared the scene. By 1:30 p.m., police publicly identified Lowdermilk and announced that evidence from the scene, including debris with traceable serial numbers, showed the hit-and-run vehicle was a 2019 to 2022 Chevrolet Silverado. The color is unknown, but investigators believe it has front-end damage.
"The pieces that were collected on the scene, the physical evidence, suggested the suspect vehicle was a 2019 to a 2022 Chevy Silverado," McPhilamy said.
