A fatal traffic crash at the intersection of E Ben White Boulevard and E Riverside Drive in Austin has led to a Murder charge for 22-year-old Casandra Barron-Manzanarez, who allegedly fled from the Department of Public Safety (DPS) following a traffic violation. According to the City of Austin official report, Barron-Manzanarez was being pursued on Wednesday, June 4, when she ran a red light, subsequently causing a collision that resulted in the death of Lisa Gail Cooper, 66.
The chain of events leading to this tragedy began when a DPS trooper attempted to stop Barron-Manzanarez's vehicle for a violation that turned into a chase. Although the trooper lost sight of the suspect's car, the authorities managed to link the suspect to the fatal incident through electronic data, despite initial thoughts that the vehicle they pursued was not the same one involved in the crash. The collision pushed Cooper's vehicle into the path of a truck, ultimately leading to fatal injuries that Cooper succumbed to at a local hospital. She was pronounced deceased, marking Austin's 42nd homicide of 2025.
Investigations by the Austin Police Department's (APD) Vehicular Homicide Unit, bolstered by search warrants for electronic data, revealed inconsistencies in Barron-Manzanarez's initial statements. It was determined that she had actively evaded arrest at the time of the collision. "Because the fatal collision with Ms. Cooper occurred during the course of this felony, the charge was classified as Murder," states the communication issued by the APD. A warrant for Barron-Manzanarez’s arrest was issued on August 15, and as of now, she has not been taken into custody.
In the aftermath of the crash, local authorities are seeking any additional information that the public might provide. They urge anyone with insights to contact APD's Vehicular Homicide Unit directly or to remain anonymous, utilizing the Capital Area Crime Stoppers Program, hinting that perhaps the smallest piece of evidence could be the break needed in capturing the subject at large. Last year's statistics for the same date thoughtfully illustrate an increase in fatal crashes in Austin, with last year's toll being 33 fatal crashes resulting in 34 deaths, compared to this year's 38 fatal crashes and 42 fatalities.
