Federal agencies launched separate probes into a June 19 crash in Katy, Texas, in which a Tesla Model 3 struck a residence, killing 76-year-old Martha Avila and injuring Justin Barbour. The driver, Michael Butler, told law enforcement he had engaged Autopilot. The Avila family filed a civil suit in Texas state court the day before NHTSA acted, with NTSB announcing its investigation two days later.
