Shipping tycoon Angela Chao was drunk when she inadvertently reversed her Tesla into a pond and drowned last month at a Texas ranch, police say.
Blanco County Sheriff’s Office found her blood alcohol level was nearly three times the state’s legal limit.
The 50-year-old died after dinner on 10 February with a group of friends at the estate near Johnson City.
Her brother-in-law, Senate Republican leader Mitch McConnell, cited the tragedy in his resignation speech.
On Wednesday, Blanco County Sheriff’s Office released the findings of its investigation concluding Ms Chao’s death was an “unfortunate accident”.
It’s pretty unlikely she got into the vehicle to do donuts on the front lawn. It is pretty likely she was gonna enter public roads while intoxicated behind the wheel, and I applaud her for preventing herself from doing it. Permanently.
