Two people were killed and several injured in a crash along Interstate 24 in Rutherford County early Thursday morning.
The crash was reported just after Midnight along I-24 east at mile marker 81, near the South Church Street exit.
Preliminary reports indicate that traffic congestion from an earlier late-night wreck caused traffic to come to a stop. A tractor trailer was unable to stop in time and struck multiple vehicles.
Two tractor-trailers and seven other vehicles were involved in the wreck. Two of those vehicles were fully engulfed in flames.
A sheriff's officer and THP officer are credited for putting one of the fires out with extinguishers, saving the victims inside.
The two other victims in the other car, identified as 28-year-old Brandon Wilson and 25-year-old Deja Morris, were unable to escape in time and died.
Officials told Nashville's News 2 five others also sustained injuries. Three of the injured were taken via LifeFlight helicopter to Vanderbilt University Medical Center and the two others were taken to Vanderbilt by ambulance.
Three of the transported patients have since been treated and released, while two others were last listed in stable condition.
Another victim underwent surgery Thursday morning.
Officials told Nashville's News 2 some of those involved were traveling to the Bonnaroo Music Festival.
A HAZMAT crew was called to the scene because one of the tractor trailers was carrying plastic pellets, but officials said it wasn't a chemical hazard.
The roadway was closed for several hours, but all three lanes of traffic have since reopened.
Authorities said the at-fault driver has been cited for failure to exercise due care.
Additional charges are pending.
