Man, 24, killed in Boulder Canyon truck crash

BOULDER, Colo. — A Thornton man was killed when his three-axle truck lost control Tuesday morning in Boulder Canyon.

The man, identified by the Boulder County Coroner’s Office as Omar Enrique Silva Marmolejo, 24, was driving an empty asphalt truck east on Boulder Canyon Drive when it appeared the truck lost its ability to brake and wrecked about 10:30 a.m., said Colorado State Patrol Capt. Stephen Bellinger.

A witness who was driving behind the truck when it lost control told Bellinger that the truck’s tires were smoking and that the brake lights were flashing on and off, but the truck didn’t slow down.

The truck crossed into oncoming traffic and ran into the side of the mountain at about mile marker 32, removing at least one tree before landing upside-down on boulders, Bellinger said.

Skid marks found about a mile west of the accident suggested the driver lost control before the turn and was gaining speed, he said.

Marmolejo, who was ejected from the vehicle, was pinned under the tractor and pronounced dead at the scene, Bellinger said.

Emergency officials from the Sugarloaf Fire Department, Boulder County Sheriff’s Office and State Patrol responded to the accident, which closed traffic between Barker Reservoir and Sugarloaf Road for most of the day
