Jonesboro Road was shut down for several hours for police to investigate and clean up the pork products.
A witness, Vielka Chavarria, previously told Channel 2 Action News it appeared the tractor-trailer was forced off the road when another vehicle cut in front of it. She saw a passenger car pull into the shopping center after the crash and then speed away.
"I think he tried to avoid the other car, and that’s when he lost control and rolled down," Chavarria said.
Three witnesses gave different accounts of the moments before the crash, and investigators told Channel 2 they are not ruling out foul play because the driver of the tractor-trailer had head trauma.
The truck flipped onto its side on Jonesboro Road in Clayton County around 12:30 p.m. Sunday.
