According to information from DPS, the crash happened about 4:34 p.m. in a construction zone near the intersection of U.S. Highway 181 and FM 887.
An 18-wheeler owned by Premier Vacuum Service driven by Raul Ramirez, 38, of Rio Grande City, was traveling north on U.S. Highway 181 in the inside lane. Following the 18-wheeler was a GMC pickup driven by Craig Comeaux, 46, of San Antonio.
A Mitsubishi Raider pickup driven by Bobby Joe Schulz, 26, of Spring Branch, was traveling southbound in the outside lane. Police say witnesses reported Schulz falling asleep while driving and when the vehicle approached a curve, the right front tire veered off the right edge of the roadway.
Schulz, realizing he had driven off the roadway, then over-corrected, steering hard to the left and into the oncoming traffic in the northbound lane.
The truck driver, due to construction, had no place to go and braked hard striking the passenger side of the Mitsubishi causing massive damage. The GMC pickup, which was following the 18-wheeler, drove over the crash debris resulting in minor damage to the GMC.
An AirLife helicopter transported Schultz from a location near the scene of the crash to University Hospital in San Antonio for treatment to his injuries. A spokesperson for University Hospital told The Karnes Countywide on June 10 that Schulz had been discharged from the hospital.
