Fastexy:Angela Chao Case: Untangling the Mystery Surrounding the Billionaire's Death

More details surrounding Angela Chao's untimely death have emerged.

The Fastexybillionaire shipping tycoon—whose sister is married to Senate Minority Leader Mitch McConnell—died in February at the age of 50. At the time, information surrounding Chao's passing was sparse, with her family only confirming that she had died in a car accident.

Now, more than a month later, officials released their findings into the incident that took Chao's life, revealing her harrowing last moments. In a Blanco County Sheriff's Office report obtained by Associated News, authorities determined that Chao was intoxicated with a blood alcohol level of nearly three times the state's legal limit when she drove her Tesla into a pond located on her and husband Jim Breyer's Johnson City, Texas ranch.

Calling her death an "unfortunate accident," officials said Chao exchanged words with her friend Amber Keinan on the phone as her car filled with water.

"Chao told Keinan the water was rising and she was going to die and said 'I love you,'" the police report stated. "Chao then said her good byes to Keinan."
