News Summary

Agustin Guillen, 38, tragically lost his life in a rollover car crash on Interstate 35. Previously charged in a fatal hit-and-run incident, his death has raised questions about road safety. Two bystanders died while assisting Guillen after the crash, and the driver who hit their vehicle now faces manslaughter charges as the investigation continues.

Round Rock, Texas – Agustin Guillen, 38, died in a car crash on Interstate 35 early on June 29. Guillen was previously charged in connection with a hit-and-run incident in May that resulted in the death of motorcyclist Shawn Oveisi, 47, in Austin.

The incident involving Oveisi took place on May 6 in the 2900 block of North MoPac northbound, where Guillen allegedly struck Oveisi’s motorcycle and then fled the scene. Following the accident, Guillen reported his vehicle stolen, a claim authorities suspected was fabricated in an attempt to evade accountability for the crash. Guillen was apprehended on June 11 for the hit-and-run but was released the next day after posting bond.

On the morning of June 29, approximately at 2:30 a.m., Guillen was driving a silver Toyota when he became involved in a single-vehicle rollover crash on Interstate 35 near U.S. 79. After the accident, two bystanders, Maximo Ramirez, 48, and Quinn Stegall, 21, exited their vehicles to help Guillen. Unfortunately, Kearra Thomas, 22, crashed into Guillen’s overturned vehicle, leading to the deaths of both Ramirez and Stegall. As a result, Thomas now faces two counts of manslaughter for their deaths. Investigators are also exploring whether her actions may have contributed to Guillen’s fatal accident.

On June 30, Travis County prosecutors dropped the felony charge against Guillen following his death the previous day. The circumstances surrounding the events leading to Guillen’s death and the subsequent charges against Thomas remain under investigation as officials seek to clarify the chain of events on that fateful night.

Details of the Hit-and-Run Incident

The initial incident that led to Guillen’s legal troubles occurred when he allegedly collided with Oveisi’s motorcycle while driving recklessly. Eyewitnesses reported seeing Guillen speed away from the scene immediately after the collision. Oveisi was pronounced dead on-site, leading to an outpouring of grief from the community, particularly among local motorcyclists.

Developments Following the Hit-and-Run

In the aftermath of this tragedy, Guillen attempted to distance himself from the incident by filing a report about his vehicle being stolen. Law enforcement officials quickly scrutinized his claim, ultimately leading to his arrest for the hit-and-run on June 11. Despite having been charged, Guillen managed to secure his release just one day later, setting the stage for the tragic events that unfolded later in June.

Fatal Crash and its Aftermath

Guillen’s fatal crash on June 29 involved a rollover incident that prompted good Samaritans to stop and assist. Unfortunately, Kearra Thomas’s vehicle collided with Guillen’s overturned Toyota shortly thereafter, leading to the preventable deaths of two individuals who were trying to help. Thomas now faces serious legal repercussions, and authorities are examining the complete circumstances of the accident.

Future Investigations and Legal Implications

The investigation into the fatal June crash and the ongoing probe regarding Guillen’s earlier hit-and-run case raise important questions about both road safety and accountability in tragic vehicular accidents. The legal ramifications for Kearra Thomas and the community’s response to these traumatic events will likely unfold over the coming months as investigations continue and the legal process takes its course.

As details emerge from this unfortunate series of events, the Round Rock community and law enforcement officials remain focused on understanding all layers of this incident to prevent future tragedies on the road.
