The Colorado State Patrol is investigating an early-morning crash Sunday that left a Ellicott teenager injured.
Troopers were called to Big Springs Road, near Calhan, just after 7 a.m.
Troopers say a 1996 Pontiac driven by 22-year-old Brian Munoz-Villar from Denver swerved out of control when the driver tried to avoid a slower vehicle.
The Pontiac spun off the roadway and flipped, throwing Munoz-Villar and his passenger, 18-year-old Luis Gill of Ellicott, from the vehicle.
Gill was hospitalized with serious injuries, troopers said. Munoz-Villar suffered minor injuries, troopers said.
"Munoz-Villar was not wearing his safety belt at the time of the crash and is suspected of driving under the influence of alcohol," troopers said.
The crash remained under investigation.
