WATCH: Insane Video Shows 70 MPH Tesla Slam Into Grandmother’s Home

A woman was killed on Friday night after a Tesla crashed into her home in Katy, Texas, authorities said.

Martha Avila, a 76-year-old grandmother, was putting away groceries when the Tesla plowed into her home. Avila was airlifted to a nearby hospital where she later died, the Harris County Sheriff’s Office said.

The doorbell camera captured the Tesla Model 3 driving about 70 mph through the residential neighborhood before speeding across the lawn and crashing into Avila’s brick home. 

Michael Butler, the 44-year-old Tesla driver, said the car was in autopilot mode when it slammed into the house. Butler was also injured and taken to the hospital. He showed no signs of intoxication and cooperated during the investigation, the sheriff’s office said.

Officials are actively investigating the crash and whether the Tesla’s autopilot system was functioning properly. They have not identified what caused the Tesla to veer off the road and crash at high speeds.

The crash left severe structural damage to the house, and the family temporarily relocated to a hotel, according to neighbors. A spokesman for Zehl & Associates, the law firm representing Avila’s family, said they planned on filing a lawsuit.

Tesla CEO Elon Musk responded to a news story about the crash on X, writing, “Yes, this makes no sense. [Full self-driving] drives slowly through neighborhood streets and this was a high speed crash!”

Automotive analyst and consumer advocate Lauren Fix told The New York Post that the Friday night crash is one of many concerns regarding Tesla’s self-driving technology.

“The mistake was calling it autopilot,” Fix said. “When someone dies in a car at that kind of speed in a neighborhood … there’s obviously either a software issue … or could be a driver issue.” 

“This remains an active and open investigation,” a Harris County, Texas, Sheriff’s Office spokesman told the Post. “Once all evidence has been gathered, it will be presented to the Harris County District Attorney’s Office to determine whether charges are appropriate.”
