A Colorado man high on cannabis edibles crashed into a Wyoming woman and broke both her femurs, court documents say.

The felony case against Sean Brandon Lahti, of Wellington, Colorado, rose to the Laramie County District Court on Monday.

Lahti, who turns 24 this year, is charged with one count of causing serious bodily injury via impaired driving and faces up to 10 years in prison and fines of between $2,000 and $5,000 if convicted.

Wyoming Highway Patrol Trooper Jason Simmer responded Feb. 19 at about 3:30 p.m. to a crash on U.S. Highway 85 in Laramie County. He found a 2022 Kia Seltos and a 2015 Jeep Wrangler, both crashed, according to an evidentiary affidavit filed last month.

Multiple witnesses on scene indicated that the Jeep, driven by Lahti, was traveling northbound and crossed into the southbound lane, hitting the Kia head-on, says the affidavit.

Evidence on scene reportedly indicated the same.

The young woman was taken by helicopter to an out-of-state medical facility. Her online presence indicates she’s in her mid-20s and was a University of Wyoming attendee as recently as 2020.

An ambulance took Lahti to the local hospital, where a trooper followed to investigate.

The trooper learned Lahti “had previously consumed edible cannabis,” says the affidavit.

During a field sobriety test, Lahti reportedly demonstrated eyelid tremors, quick and exaggerated movements, irregular pupil dilation and a “very high pulse rate.”
