Minutes later on the same highway, a gunman shot and killed 42-year-old William Scott Miller, the driver of a United Van Lines rig, Miller said.

Police said the driver, a military veteran who was about to fly home to his wife and two young daughters in Frankfort, Ky., for the holidays, was able to bring his truck safely to a stop before he died.

"The act he did in and of itself I consider to be heroic," Miller said. "Despite being mortally wounded, he was able to control his rig to the point where other drivers weren't injured."

Duty first. 

Now is the time at Castle Argghhh! when we dance: In Memoriam for William Scott Miller.
