Marijuana Suspected As Factor in Fatal Friday Crash South of Longmont

July 19, 2016

Colorado State Patrol investigators suspect marijuana was a factor in a two-vehicle crash that killed both drivers Friday at U.S. 287 and Plateau Road south of Longmont, Trooper Nate Reid said Tuesday.

However, Reid said the cause of the crash will be further investigated by the Boulder County Coroner, which could take several weeks. He could not provide specifics about why marijuana was suspected.

“The investigator on scene must have some indicator that marijuana was involved,” he said.

A green Subaru Outback driven by Allen Leszczynski, 46, of Aurora was heading northbound on U.S. 287 shortly after noon when it crossed into the southbound lane and struck a green Honda Accord driven by Vincent Perez, 68, of Longmont.

State Trooper Alisha Danko previously said that the two vehicles collided on the drivers’ sides and spun around, and the Accord struck a guard rail. Perez died at the scene and Leszczynski was airlifted to Boulder Community Health’s Foothills Hospital where he later died .

There were no passengers in either vehicle.
