A minivan trying to overtake a vehicle in a no-passing zone on a Texas highway crashed head-on into an SUV, which was then rear-ended by another vehicle, authorities said. Six people suffered a wrongful death in the crash and five others were injured.

The crash happened around 6:20 p.m. Friday near George West, about 60 miles northwest of Corpus Christi according to the Texas Department of Public Safety.

The crash remained under investigation Monday, according to the Texas Department of Public Safety. But the department said in a news release that a minivan traveling south on U.S. Highway 59 tried to pass in a no-passing zone and crashed head-on into the northbound SUV. A sedan then slammed into the back of the SUV.

The vehicle that was being passed was not hit in the crash according to the Texas Department of Public Safety.

The driver of the minivan, Xochitl Veronica Lopez, 39, of Houston, died at the scene, along with a juvenile passenger in the minivan, the department said.

The driver of the SUV, Salvador Almeda Mendoza, 47, of Ganado, Texas, was also killed, along with two passengers, Ilda Briones Nieves, 58, and Honorio Lazo Navarro, 74, both of Ganado.

The sixth person killed was a passenger in the sedan whose name has not been released.

Five other people were taken to a hospital with ‘non-incapacitating injuries,’ the public safety department said.

Authorities so far don’t believe that alcohol was a factor.
