Manhattan District Attorney Cyrus R. Vance, Jr. disclosed the details as he announced the indictment of 26-year-old Stefan Hoyte, whose car crashed into a pillar on the bridge on March 16th.
The accident killed 21-year-old Amanda Miner, who was thrown from the vehicle.
Hoyte is charged with manslaughter, vehicular manslaughter, and operating a motor vehicle while intoxicated.
"In the hands of an intoxicated driver, a vehicle can become a powerful weapon capable of destructive and deadly force," said Vance. "In this horrific case, the defendant is charged with drunkenly slamming into a pillar in such an unwieldy, uncontrolled manner and at such a dangerously high speed that the impact severed the victim in two."
Vance said Hoyte was driving the victim and her boyfriend home from a Manhattan bar at about 3 a.m., heading eastbound on the Williamsburg Bridge.
He lost control and struck a pillar dividing the inner and outer roadway of the bridge.
A black box recovered from the vehicle revealed that Hoyte had been driving at a speed of 111 miles per hour in the seconds before the crash, said Vance.
He said a hospital blood draw taken shortly after the arrest showed Hoyte had a blood alcohol level of .12.
Miner, an aspiring social worker from Williamsburg, died one day after her 21st birthday.
