The driver who troopers say caused a three-car wreck that killed two people on Saturday is suspected to have been under the influence of alcohol.

Colorado State Patrol says a black Jeep was traveling south in an Interstate 25 northbound HOV lane near 58th Avenue and hit a Honda CRV head on just before 6 p.m.

Miguel Ramirez Gutierrez, 47, was driving that CRV. He was killed. A 17-year-old boy in his vehicle who troopers would not name was also killed. Two women in that car suffered serious injuries.

The driver of the Jeep, Kimberly Rodriguez Roldan, 24, also suffered serious injuries.

A third vehicle was struck on the rear of its driver's side by the CRV, causing it to rotate out of control. That driver was uninjured.

Troopers say Rodriguez Roldan faces possible charges of vehicular homicide and vehicular assault.
