• Shipping magnate Angela Chao drove her Tesla into a pond while on a ranch with friends.
  • Police initially conducted a criminal investigation, and questions were raised about Tesla controls.
  • Chao's blood-alcohol concentration was 0.233. Police concluded her death was an accident.

Angela Chao, the shipping magnate who drowned after backing her Tesla into a pond on her Texas ranch, had a blood-alcohol level nearly three times the legal limit when she died, newly released police records show.

Chao was the CEO of Foremost Group, the wife of venture capitalist Jim Breyer and the sister of former cabinet secretary Elaine Chao, the wife of former Republican Senate leader Mitch McConnell.

Chao's sudden death occurred in Blanco County, outside Austin, on February 11. Local police initially declined to share many details, saying they were still investigating.

On Wednesday, the Blanco County sheriff released 62 pages of records. The documents said Chao's death was an "unfortunate accident." It also said that her blood-alcohol concentration was 0.233 grams per 100 milliliters, which is about three times the legal limit of 0.08 grams per 100 milliliters.

Chao planned to drive from one building on the ranch to another because it was cold outside. But she accidentally reversed into a pond shortly after getting into her car, police said.

The report describes how Chao's friends, an employee, and first responders attempted to save her from the pond she'd driven into on the remote ranch. Even though one of the back doors of the car was open, officers could not pull her out of it, and it took them several minutes to break the driver's side window and extract her body.

Chao called a friend from the submerged vehicle and told her she loved her and that she could not open her door, according to the police report. According to The Wall Street Journal, which previously reported details of Chao's death, Chao also said that she had accidentally put the vehicle into reverse before.

Business Insider previously reported that several Tesla owners had told federal authorities about confusion and dangerous situations that they blamed on their vehicles' unconventional gear-shifting mechanisms.

The Journal reported that Chao's family did not blame Tesla for her death.

"Angela's passing was a terrible tragedy, and words cannot describe the family's profound grief," a spokesman for the family of James S.C. Chao, Angela's father, said in an emailed statement. "The family is grateful for the first responders and friends who tried so hard to save her."

Correction — An earlier version of this story said Chao's death did not make national headlines until weeks after it occurred. The story has been updated to reflect her death was publicly reported on February 14, three days after.
