The driver of a vehicle involved in a fatal crash in 2011 has received his sentence.

Tanner Vasquez of Casper, was sentenced to serve seven-to-eight years in prison after pleading guilty to two charges of aggravated vehicular homicide.

Prosecutors and witnesses say on Halloween Day 2011, Vasquez was driving north on Bryan Stock Trail near the Amoco Road intersection at a high rate of speed.

Vasquez sideswiped a vehicle that had stopped at the intersection and then Vasquez drove into a ditch.

Two of four people in Vasquez’s car died as a result of injuries sustained from the crash.

Seventeen-year-old Anthony Prince died at the scene, while 21-year-old Jeremy Conrad later died at the Wyoming Medical Center.

Vasquez was placed on life support at the hospital’s intensive care unit and later recovered, while a fourth person survived with unknown injuries.

Police say none of the occupants in the vehicle were wearing their seat belt at the time of the crash.

An accident reconstructionist says the vehicle was going at least 54 miles-per-hour at the time it crashed into the ditch.

Upon further investigation, officers found two cans of Dust Off inside Vasquez’s vehicle and a blood test confirmed that Vasquez had inhaled some of it.

Vasquez has also been ordered into the intensive treatment program.
