by Tesla driver charged with involuntary manslaughter after fatal crash in Texas
Late last month, a Tesla Model 3 crashed into a house, killing an elderly woman inside. The driver, according to preliminary data, blamed the incident on the Full Self-Driving system. Elon Musk and one of his executives claimed the driver was pressing the accelerator pedal. Authorities have now filed charges that appear to support Tesla’s version. Despite this, the deceased woman’s family is suing the automaker.
Charges and investigation data
Harris County Sheriff Ed Gonzalez announced that 44-year-old Michael Butler has been charged with involuntary manslaughter in connection with the June 19 crash that killed Martha Avila. According to investigators, Butler’s Tesla left the roadway in a Katy neighborhood, breached the front wall of a home, and struck Avila, who later died from her injuries.
Although Butler told investigators he was using the Full Self-Driving system while delivering for DoorDash, authorities claim the car’s data paints a more complex picture. According to KPRC, investigators downloaded information from Tesla’s electronic systems, including video recordings, accelerator pedal depression metrics, braking data, steering information, and speed records.
Lack of braking evidence
Most damaging to Butler’s defense is what investigators say they did not find. Authorities report no evidence of braking during the final minute before the collision. They also claim checks found no mechanical defects, a stuck accelerator pedal, or obstructions from floor mats that could have caused the crash.
Investigators also checked Butler’s mobile phone and reportedly found Google search queries made weeks before the crash that expressed frustration with Tesla’s Full Self-Driving system. A medical examination after the incident found no signs of a seizure, stroke, heart attack, alcohol intoxication, or other narcotic substances.
Federal investigation and lawsuit
The case has also drawn attention at the federal level. NHTSA has opened a special investigation into the crash to determine if Tesla’s technology played any role in the incident. Avila’s family has filed a wrongful death lawsuit against Butler and Tesla, claiming the automaker’s Autopilot and Full Self-Driving systems were defective, and also accusing Butler of negligent operation of the vehicle. The family is seeking damages in excess of $1 million.

This case highlights the complexity of investigating crashes involving autonomous driving systems. While the car’s data suggests the driver was actively pressing the accelerator rather than relying on autopilot, questions remain about whether Tesla’s technology could have misled the driver or created a false sense of security. The deceased’s family lawsuit, as well as the federal investigation, indicate that responsibility may be shared between the driver and the manufacturer. This case is likely to set a precedent for future legal disputes over the safety and liability of semi-autonomous driving systems.
