COLUMBIA (WACH / AP) -  A man has died after being struck and killed by a truck outside the Dorn Veterans Administration Medical Center in Columbia.

Columbia police spokeswoman Jennifer Timmons says the Tuesday morning death appears to be an accident, but officials are still investigating.

Richland County Coroner Gary Watts says 85-year-old Duane Mack of Gilbert was leaving the VA hospital when he was run over around 10 a.m. Tuesday.

Police say a person, whose name has not been released, was trying to park a pickup truck on the hospital complex when they hit the accelerator instead of the brake, causing the vehicle to hit Mack and run into a building.

Timmons says Mack was walking on the sidewalk while being assisted by another person.

Mack was transported to an area hospital where he died from injuries sustained from the collision.

Timmons says no one else was hurt.
