Chesnee police officer Tim Walker said he had no choice but to try and stop a driver-less truck that was out of control and had already injured one man.
"I got a call about a pedestrian involved accident," Walker said. "When I got their I found a truck doing circles in reverse."
Frederick Watkins had been working on the truck moments before when things went wrong.
"I was trying to crank it," Watkins said. "It cranked and I must have left it in reverse. I tried to catch it but I didn't do much of that."
Watkins doesn't remember the truck hitting him and knocking him out or mailman Rusty Tucker stopping to pull him from danger.
"I saw a man laying in the parking lot bleeding and the truck was coming closer," Tucker said. "I finally got him on his feet and he was able to walk and sit down on a chair."
By the time Walker got on scene Watkins was safe but the truck was still going, and still a danger according to the officer.
Dash cam video released to FOX Carolina shows Walker approach the truck looking for a way to stop it.
"I tried jumping in the door but it knocked me into the road," Walker said.
Undeterred, Walker then tried again and this time succeeded by jumping into the bed of the truck, busting out the back window, then crawling in and putting the truck in park.
On Thursday Walker and Watkins met for the first time since the accident. Watkins thanked Walker for what he did and Walker apologized to the 84-year-old for busting his window.
Walker was also quick to tell Watkins that in his mind Tucker deserves all the credit for his quick action.
Tucker said he was just a mailman trying to deliver some help to a neighbor.
"I try to do more than just deliver the mail," Tucker said."I try to be a public servant in every way I can."
Watkins is now at home recovering from his injuries and said he plans to sell his truck.
