SALISBURY — The reconstruction and details of a Tuesday morning collision that killed 66-year-old Treva Waller could take weeks.

No charges have been filed, but a police reconstructionist is looking to determine what exactly happened, said Salisbury police spokesman Lee Walker.

Waller, who was leaving Alligood Automotive, crossed the roadway headed toward the McDonald’s/Ruscho gas station when she was struck along the driver’s side by a tractor-trailer. The tractor-trailer was from BMC East, a building materials company based in Youngsville, Walker said.

The driver, Larry Stewart, of Kernersville, made his first run in Mint Hill, reloaded and was headed to Woodleaf. He was hauling wooden tresses, Walker said.

The Mustang had significant damage on the driver’s side. According to police, Waller was pinned inside the vehicle and she died at the scene. The Mustang came to rest facing the opposite direction near the McDonald’s entrance. The tractor-trailer came to rest a few yards away. The load it was carrying had shifted slightly but was still aboard the flatbed.

It could take the Salisbury Police Traffic Safety Unit weeks to conclude its investigation. After the collision, the road remained closed so that the reconstructionist could collect data from the crash scene. Salisbury Fire Department, Salisbury Police and the State Highway Patrol responded.

The highway patrol’s motor carrier division was on hand to conduct an inspection. The details of the report were not immediately available.
