The fatal crash happened in the 1900 block of Blooming Park Lane, where investigators say Butler’s Tesla was traveling at a high rate of speed when it failed to make a turn, left the roadway and crashed through the front wall of a home.
Authorities say Avila was inside the home when she was struck. She was taken to a hospital, where she later died from her injuries.
Investigation into Tesla technology continues
Investigators have been working to determine whether Tesla’s driver assistance technology played any role in the deadly crash while also examining Butler’s actions leading up to the collision.
According to investigators, Butler initially told deputies the Tesla was operating on Autopilot at the time of the crash. However, the Harris County Sheriff’s Office later said Tesla provided vehicle data indicating Butler had overridden the system before the collision.
Sheriff Ed Gonzalez also said investigators have not found any evidence of a mechanical malfunction with the Tesla so far.
The National Highway Traffic Safety Administration (NHTSA) has launched a special crash investigation into the incident. Federal records show the agency has spent years examining crashes involving Tesla’s Autopilot and other advanced driver assistance systems.
Family sues Tesla and driver
The criminal charge comes about a week after Avila’s family filed a wrongful death lawsuit against both Butler and Tesla.
The lawsuit, filed by Avila’s daughter, Jennifer Barbour, and son-in-law, Justin Barbour, alleges Tesla’s Autopilot and Full Self-Driving systems were defective and failed to prevent the crash. The family also claims Butler was negligent in operating the vehicle.
According to the lawsuit, the Tesla crashed through the front of the family’s home while Avila was inside. Justin Barbour was also in the home and suffered injuries to his neck, back and shoulders, according to court documents.
The family is seeking more than $1 million in damages.
