A 73-year-old Robstown woman was killed and a Corpus Christi man injured in a two-vehicle fiery crash last week along U.S. Highway 77 in Robstown.

Pomposa Perales, of Robstown, was pronounced dead at the scene of the Jan. 9 crash while still inside her torched sport utility vehicle.

Wade Secrest, 40, of Corpus Christi, suffered minor injuries, including an arm injury, during the morning accident and was taken by ambulance to Christus Spohn Memorial Hospital.

Robstown police and firefighters were dispatched to U.S. Highway 77, between FM 892 and County Road 36, at about 11:11 a.m. in reference to a major traffic accident involving two vehicles that were on fire.

Police said the accident occurred as both drivers were traveling alone southbound on Industrial Boulevard.

Perales had stopped or slowed to merge on U.S. Highway 77 when her SUV was struck from behind by Secrest's car, police said. Both vehicles caught fire as Secrest's car crashed into the ditch where the roads merge, while Perales's SUV continued for several hundred feet on the highway.

Seacrest managed to extricate himself after the crash, while Perales did not.

Robstown police and Ric Ortiz, investigator for the Nueces County Medical Examiner, said the investigation remains ongoing.

"We believe that the reason the car ignited is because one of the gas tanks ruptured and that one of the vehicles' parts ignited the fuel," said Robstown Police Department Lt. Gilbert Gomez.

No charges had been filed as of Tuesday.

"We're still investigating and we're going to be meeting with the district attorney's office to determine that," Gomez said. "At this time charges are pending,"

Southbound traffic along Highway 77 was re-routed for about two hours.
