Driver in deadly Katy Tesla crash charged with manslaughter

Michael Butler, 44, was booked into the Harris County Jail on Wednesday, July 1, and charged with manslaughter in the deadly Katy-area Tesla crash that killed 76-year-old Martha Ávila inside her home. Harris County Sheriff Ed Gonzalez said the charge is tied to the June 19 wreck that tore into a residence in the 21300 block of Rose Hollow Lane near Blooming Park Lane and Park Brush Lane.

Investigators said Butler was driving a Tesla Model 3 eastbound on Rose Hollow Lane when he failed to maintain a single lane, left the roadway and slammed into the brick home. Local reports placed the crash at about 8:03 p.m. and described the scene as violent enough to destroy part of the house and leave nearby neighbors shaken. Ávila was airlifted to a hospital and later pronounced dead.

The crash has quickly become more than a traffic case. Deputies said Butler told investigators that an automated driving-assistance system was engaged at the time of the wreck, while Tesla disputed that account and said the driver overrode the feature by pressing the accelerator. The Harris County Sheriff’s Office has said investigators found no evidence of a mechanical malfunction in the Tesla, sharpening the focus on driver control, speed and how the vehicle was being operated when it crossed into the home.

Ávila’s daughter and son-in-law have filed a wrongful-death lawsuit in Harris County against Tesla and Butler, and the family has publicly said it wants answers. Their case adds a civil fight to a criminal prosecution that is still in its earliest public stage, with court documents spelling out the specific allegations not yet available in the public record.

The wreck is also under federal scrutiny. The National Highway Traffic Safety Administration opened a special crash investigation, and the National Transportation Safety Board also announced it was investigating. NHTSA has previously described Tesla Autopilot as a Level 2 advanced driver-assistance system that requires human supervision, a distinction that will matter as investigators examine whether the driver, the automation system or both bear responsibility for a crash that ended in a death inside a west Harris County home. Tesla’s 2023 recall-related defect report on Autopilot adds to the regulatory backdrop, showing federal concerns about driver supervision were already on the record before this case.
