Christopher Robert Youngblood was showing off his nitrous oxide-boosted sports car to his sister and his brother-in-law, hitting 90 mph in a 45 mph zone when the vehicle veered off the road, went airborne, hit a wall, then a fence before smashing into a Kearns home.
Both passengers died in the December 2011 crash. Youngblood lived and ultimately pleaded guilty to two counts of automobile homicide.
Because tests showed Youngblood had a blood alcohol level of 0.07 — as well as marijuana in his system — the crash was tallied among the statistics that legislative proponents used to argue for a new law making Utah the first in the country to have a strict 0.
