TEMPLE, Texas -- A Central Texas woman died after someone dropped a rock from a railroad overpass through the windshield of the car in which she was riding.
Temple police asked for the public's help in identifying a suspect in the Saturday night incident on Interstate 35 that fatally injured Keila Ruby Flores. The 33-year-old Waco woman died Sunday morning at a Temple hospital.
Police said Flores was in the front passenger seat of the car driven by boyfriend Christopher Rodriguez.
Rodriguez told police that they were returning to Waco from Austin with Flores' three children in the back seat when a rock the size of a football smashed through the windshield.
"It was a loud impact almost, like an explosion that went off in the car. I didn't know what it was," Rodriguez said. "Her daughter immediately said, 'Call 911! Pull over, pull over! Call 911!"
Rodriguez tried desperately to perform CPR on her, with the help of a Good Samaritan who was driving behind the family. He said he never got to thank that person, but he's eternally grateful that they stopped to help.
"She didn't deserve that. No one deserves that. An innocent person, a good mother, a good sister. To do that? Senseless," said Luis Flores, Keila's brother.
No one else in the car was injured.
These kinds of incidents are happening with terrifying frequency. Last November, a Tennessee man was driving to work when suddenly a slab of concrete thrown from an overpass crashed through his windshield killing him. That case is still unsolved.
Also last year, a six-pound stone dropped from an overpass took the life of a young father and left the five teen boys who had been throwing rocks onto a highway below to wrestle with the difference between a prank, second-degree murder and manslaughter.
Investigators asked anyone with video of the most recent incident or information on the suspect to call Temple police.
