They thought whatever the object was might have hit a window, but when they arrived at the hospital, they noticed a hole in the trunk.
The couple said they called Belmont police and an officer found a bullet intact in the car.
"The officer said it had to be somebody on top of the bridge shooting down," Joe Wood told WSOC.
Joe Wood said he has had three heart attacks and has a pacemaker, and this was a close call he didn’t need. If the shot had been fired seconds earlier, he said it could have hit him in the driver's seat.
"I'm just was glad it didn't hit me,” he said. “I just got out of the hospital and then this happens."
Police took pictures of the car and kept the bullet for examination.
"I hope the cops catch you 'cause this is highly dangerous," Joe Wood said.
Authorities could not confirm where the shot came from since the case is still under investigation.
