Round Rock (KXAN) – The driver of a car involved in a crash last year that killed a teenage girl in Williamson County has been charged with intoxication manslaughter, according to a police affidavit filed this week.
Police said they arrived at the scene of the car crash Nov. 29, 2014, at midnight. They found a 2006 Ford Crown Victoria completely split in half. The car had smashed into a tree on Hairy Man Road, near the intersection of Great Oaks Drive. The 21-year-old driver, James H. Castellano, was transported to St. David’s Medical Center in Round Rock but was not seriously injured.
The 18-year-old passenger, Vanessa Arzola, was ejected from the car and died at the scene. Castellano was wearing a seat belt, but Arzola was not, the affidavit states.
Police say they found two small baggies of cocaine inside Castellano’s wallet at the scene. Laboratory tests indicate Castellano had cocaine, marijuana, Xanax and some alcohol in his system, according to the affidavit.
Investigators also reviewed black-box data from car. About three seconds before the recording ends, data showed the car’s throttle was fully engaged and that the car was traveling at 77 mph. The car then rapidly decelerated before the recording ends.
Castellano allegedly told police he had one drink and a nap before driving and that he was going too fast around a curve, saying the car began to hydroplane before the crash.
