A man has been arrested on manslaughter charges following a fatal crash involving his Tesla Model 3, which reportedly was in self-driving mode when it collided with a house in the Houston area, resulting in the death of a 76-year-old woman. Michael Butler, 44, was taken into custody after the incident on June 19 that claimed the life of Martha Avila. Harris County Sheriff Ed Gonzalez announced Butler’s arrest in a recent Facebook post.
Currently held at the Harris County Jail, Butler’s bail has been set at $150,000. He is expected to face a court hearing on July 6. The incident has not only led to Butler’s legal troubles but has also attracted the attention of federal investigators and prompted a wrongful death lawsuit from Avila’s family.
On the night of the crash, Butler was driving in the suburban area of Katy when his vehicle reportedly crashed through the front wall of Avila’s home, fatally trapping her. While Butler sustained injuries from the crash, investigators noted that he showed no signs of intoxication and was cooperative throughout the investigation. He allegedly informed law enforcement that he was utilizing the self-driving capabilities of his Tesla at the time of the incident. However, details surrounding whether these technologies played a role in the crash remain ambiguous.
Tesla’s executive vice president of AI software, Ashok Elluswamy, stated on social media that the driver had “manually overrode” the self-driving system by fully pressing the accelerator. CEO Elon Musk echoed this sentiment, describing the event as a “high speed crash.”
Under Texas law, manslaughter is defined as recklessly causing the death of another person and is generally considered a second-degree felony, carrying potential prison sentences of 2 to 10 years. The lawsuit filed by Avila’s family accuses both Butler and Tesla, the company founded by Musk, of gross negligence related to the crash and argues that the self-driving features of the Tesla Model 3 are defective without adequate warnings.
In the wake of the civil lawsuit, the National Transportation Safety Board (NTSB) and the National Highway Traffic Safety Administration (NHTSA) announced investigations into the incident. These inquiries add to a growing number of investigations into Tesla’s advanced driver-assistance systems, with nearly 50 special investigations initiated by NHTSA since 2016 involving crashes linked to such technologies, reportedly resulting in approximately two dozen fatalities.
Concerns have been raised regarding Tesla’s full self-driving system, particularly its ability to detect hazards in low-visibility conditions, prompting the NHTSA to escalate its investigation into around 3.2 million Teslas equipped with this technology. In 2023, the company recalled nearly all of its electric vehicles on U.S. roads to ensure drivers are attentive while using the autopilot feature.
Despite the legal and regulatory challenges it faces, Tesla appears to be regaining momentum in sales after a notable decline earlier this year amid backlash against Musk for his political engagement. Recent figures have indicated positive trends in the company’s auto business, suggesting a potential recovery following earlier setbacks.
