Trucker In Fatal Crash Under Influence Of Marijuana

Commerce City Police: Tests Show Driver's Ability 'Significantly Impaired'

One of the truck drivers in a double-fatal crash in Commerce City last May was under the influence of marijuana at the time, police said Tuesday.

Daniel Seilheimer, 41, of Colorado Springs, and George Mendoza, 52,of Adams County, died when their big rigs collided head on in the 7500 block of Quebec Parkway on May 27.

Seilheimer was southbound when police said he crossed the center median, colliding head on with Mendoza's truck. Both trucks caught fire after the crash, trapping the two drivers in the wreckage.

According to toxicology tests, Seilheimer was so influenced by marijuana that his ability to safely operate a motor vehicle was significantly impaired, police said.

"It has not been determined if Daniel Seilheimer had a medical marijuana license, however Colorado State Statute prohibits the operation of any motor vehicle while under the influence of alcohol or drugs, to include medical marijuana," officer Chris Dickey said in a news release.
