Lyman, Wyo. - The Wyoming Highway Patrol is investigating a deadly wreck that killed a Green River woman.
It happened around 2:00am on February 1st, at milepost 48 along Interstate 80 near Lyman.
Troopers say a 2013 Toyota Tundra was traveling eastbound on I-80, when the vehicle drifted off of the highway and struck a delineator post. The driver steered his vehicle to the right in effort to re-enter the roadway but collided with the bridge deck guardrail. The vehicle then rolled over the guardrail and landed on its roof.
At 6:00 a.m., a passer-by saw the crashed Toyota Tundra and called 911.
The adult female passenger, Kymbrlee Smith, 30, despite properly wearing her seat belt, was pronounced dead, and the adult male driver, Samuel Smith, 31, who was also properly wearing his seat belt, was transported via helicopter to the University of Utah Medical Center. He is currently in critical but stable condition due to head trauma. A one-year-old juvenile who was secured in a child safety seat; a three-year-old juvenile who was secured in a child safety seat; and a 10-year-old juvenile who was wearing his seat belt were treated and released to family members.
Fatigue is being investigated as a leading cause of this crash, the sixth highway fatality in Wyoming for 2018.
