A Casper man is admitting his role in a vehicle crash that killed two people in 2011.

Twenty-year old Tanner Vasquez has pleaded 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 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.

As part of a plea deal, prosecutors will seek no more than an eight year prison sentence, which will be handed down at a later date.

Vasquez is free on $75,000 bond.
