COLORADO — Shun Jones, 48, and Amanda Omo-Iyamu, 38, were struck and killed Saturday morning by a 16-year-old youth driving a tractor-trailer as they were pulled to the side of a Colorado highway while changing a flat tire.

The two women, who were cousins, were on their way from Texas to visit family members. They were accompanied by Shun’s 18-year-old son, Lamarcus Lockett, who remained in the vehicle and was unharmed.

The pair was struck by a truck that had been towing a full cargo of horses in a trailer.

Upon striking the women, the truck reportedly stopped about a half mile down the road. There were two people in the truck, Tristan Martin, 16, and 37-year-old Michel Martin of Sulphur, La. When police questioned both parties, Michel told them he had been driving the truck. After further questioning, investigators discovered Michel had lied and that the youth had actually been the one operating the rig when it struck the two women.  Both Michel and the teen sustained no injuries.

One woman died at the scene and the other was airlifted to a hospital where she was pronounced dead.

Tristan was charged with two counts of leaving the scene after an accident involving a death, felony, and two misdemeanor counts of careless driving involving death.  Michel was charged with one count of false reporting.
