DENVER (KDVR) — Deputies were investigating a possible road rage shooting Thursday on U.S. 287, which led to a fiery crash that left a nearby field and a responding ambulance in flames.

It happened in Larimer County at Owl Canyon Road and U.S. 287, and road closures lasted into the night during the investigation.

No one was hit by the gunfire, but a total of eight people were taken to the hospital with injuries from the crash, according to the Larimer County Sheriff’s Office.

“Preliminary investigation determined that unknown suspect/s in a vehicle reportedly fired shots at another vehicle. The victim vehicle crashed and caught fire, and the suspect vehicle left the scene,” the sheriff’s office said in a release.

SkyFOX was over the scene and captured an image of a minivan burnt, with the field around it charred black.

A responding ambulance also caught fire, the sheriff’s office said. But the fire did not hurt anyone. The fires have since been extinguished.

Northbound U.S. 287 was closed for the investigation, and two southbound lanes were closed as well, according to the Colorado Department of Transportation.

Several road closures were also in place Thursday night:

• U.S. 287 at County Road 80
• U.S. 287 at Ted’s Place
• Owl Canyon Road at County Road 21

All roads had reopened by about 10:30 p.m.
