San Antonio, TX — June 12, 2025, One person was killed and one was injured following a car accident at around 5:09 P.M. on TX 16 South.

According to reports, a Corvette operated by Ethan Brengal with Shawna Lanier as a passenger was traveling on Texas 16 in the southbound lanes near the intersection with West Creek Road. The vehicle was reportedly speeding when it lost control and entered the northbound lanes where it struck a guardrail before entering a creek.
First responders arrived on the scene and transported Brengal and Lanier to the hospital with serious injuries where Brengal was later pronounced deceased. Lanier’s injuries are not believed to be life threatening, and officials continue to investigate.

When a crash involves high speed and serious injuries, it’s easy to stop at the assumption that driver behavior was the whole story. But even in situations that seem straightforward, it’s worth asking whether everything that should have been examined actually was.
1. Did the authorities thoroughly investigate the crash?
Reports mention speed and loss of control, but that alone doesn’t answer how or why the vehicle veered into oncoming lanes and ultimately into a creek. Was the crash scene carefully reconstructed? Did investigators look into the trajectory, steering inputs, or whether the driver attempted to correct the vehicle’s course? With the car striking multiple obstacles before coming to rest, a thorough mapping of the sequence is necessary to determine what actually caused the crash—and whether there was any opportunity to avoid it.
2. Has anyone looked into the possibility that a vehicle defect caused the crash?
A Corvette is built for performance, but that doesn’t make it immune to failure. Tire blowouts, suspension failure, or issues with electronic stability controls could all contribute to loss of control, especially at high speeds. Without a mechanical inspection, there’s no way to know if the vehicle reacted the way it was supposed to—or if something malfunctioned at a critical moment. That’s a question worth answering, especially when the result was fatal.
3. Has all the electronic data relating to the crash been collected?
This kind of vehicle likely recorded data in the moments leading up to the crash—speed, throttle, braking, steering, and stability system activity. That information can help distinguish between reckless driving and a failed attempt to maintain control. Investigators should also explore GPS data, traffic cameras, or nearby surveillance to support or challenge what the raw data shows.
Speed may be part of the story, but it’s not the whole one. If the investigation doesn’t account for every possibility, the final picture will never be fully in focus.
Takeaways:
- High-speed crashes still need detailed reconstruction to reveal the full sequence.
- Even performance vehicles can suffer mechanical failures under stress.
- Vehicle data is key to confirming whether the car and driver responded as expected.
