Officials believe drugs may have played a role in a deadly crash on Interstate 40 Saturday morning.
According to a press release, 47-year-old Michael Giles was driving his minivan on I-40 near the I-65 split when he left the roadway.
He then ran into the back of a parked tractor trailer driven by 35-year-old Mengesha Haile, who is from Lilborn, Georgia.
Giles died at the scene. Haile, who was standing at the front of his truck at the time of the collision, was not injured.
Police said Haile stopped on the shoulder, several feet off the Interstate after he had mechanical problems.
Reflective triangle warning signs were behind the trailer to notify drivers.
Police said there was evidence that drugs may have been involved on the part of Giles.
Officials will perform blood tests to confirm the cause of the crash.
