Ramiro Gonzalez Cavazos, 44, of Edinburg, and Robert Wayne Nabors, 61, of Como, were both killed in the accident.
Claude Everett Leach, 34, of Bigfoot, survived the collision, according to the accident report filed by Trooper Aaron Frazier of the Department of Public Safety.
McMullen County Judge James Teal pronounced the drivers dead at the scene at 10:21 a.m. and 10:25 a.m., respectively.
Traveling in the westbound lanes, Cavazos’ rig, a 1994 GMC tractor towing a 1979 load belly dumper, veered into the eastbound lanes and sideswiped Leach’s rig, a 2012 Peterbilt towing a 2011 drag tanker before stiking head on Nabor’s rig, a 2012 Mack Truck towing a 2011 drag tanker.
Leach’s rig rolled one- and-a-half times before coming to rest on its drivers side off the roadway and facing south.
Nabors’ truck came to a rest upright on the roadway facing south, and Cavazos’ truck came to a rest on its passenger side off the roadway facing east.
Cavazos was wearing his seat belt but was ejected from the vehicle and landed on the trailer, the report said.
Leach was extricated from his truck after emergency personnel worked 45 minutes, using the Jaws of Life to free him.
Leach was transported by an Airlife helicopter to University Hospital in San Antonio with critical internal injuries, according to the report.
Because of the accident, State Highway 72 was closed until about 5:30 p.m. Monday so the 18-wheelers could be hauled off and the roadway cleared.
Also at the scene were the McMullen EMS, McMullen Volunteer Fire Department, McMullen County Sheriff’s Office, Live Oak County Sheriff’s Office, Live Oak County Volunteer Fire Department and Acadian ambulance service.
