MEXIA, Texas - Gov. Greg Abbott has joined law enforcement officers from across the state in paying tribute to a Texas state trooper who was shot and killed during a traffic stop on Thanksgiving Day.

The funeral for Trooper Damon Allen was held Friday at a high school about 40 miles northeast of Waco.

Allen, a married father of four children, was a trooper for 15 years and was the first to die in a shooting incident since 2008.

Authorities say he was in his car after making a traffic stop when the driver of the other vehicle stepped out and fired a rifle at him. Allen died at the scene.
