A tow truck driver was struck and killed on the shoulder of Highway 77 northbound near Woodsboro, Texas, on Thursday, March 31. According to news reports, Christian Gutierrez, 24, was loading a vehicle that had been in an unreported accident when he was hit by a UPS tractor-trailer, Refugio County police said. Gutierrez worked for Coby’s Auto and Wrecker Service in Victoria.

The driver of the UPS tractor-trailer, Steven Booker, 44, of Houston, did not stop after striking Gutierrez, a three-time Iraq combat Marine veteran, and told troopers of the Department of Public Safety that he did not know his rig hit the operator.

Gutierrez’s death comes a day after the Texas Senate approved a Move Over bill requiring motorists to slow 20 miles per hour under the speed limit or change lanes when passing tow trucks at work on the roadside.
