JEFFERSON COUNTY, Colo. — One person died in a three-vehicle crash off US Highway 285 at State Highway 8 Monday morning, according to the Jefferson County Sheriff's Office.
According to the Colorado State Patrol (CSP) preliminary investigation, troopers believe the 33-year-old male driver of an Acura IRL had been driving southbound on northbound Highway 285 when he hit a Cadillac CTS, causing it to spin out of control and hit a Chevrolet Colorado with two people inside.
The 59-year-old man who was driving the Cadillac CTS was transported to a hospital, where he later died. His passenger, a 64-year-old woman, was brought to the hospital with life-threatening injuries.
The driver of the Chevrolet, a 51-year-old man, was also hospitalized as a precaution for minor injuries, CSP said.
The 33-year-old in the Acura — who is accused of causing the crash — was transported to a local hospital for serious injuries.
The highway reopened in both directions at 11:16 a.m.
As we tracked this crash on Monday morning, Denver7's Traffic Expert Jayson Luber observed firefighters working to get people out of two of the vehicles on northbound US 285 after the crash happened around 5:19 a.m. Luber saw first responders pull one person from a car and get that victim into an ambulance.

During the closure, drivers were asked to take alternate routes.
Luber advised drivers to take Highway 8 all the way to Morrison and then back to C-470. Or they could take a right turn just after The Fort restaurant on S. Turkey Creek Road, take it under U.S. Route 285 and wind their way to W. Quincy Ave. and C-470.
State patrol is leading the investigation into what happened.
Anyone who witnessed the crash and has not spoken to investigators is asked to call CSP Patrol Dispatch at 303-239-4501.
