This morning Boise Police Detectives arrested Bryan Grensing following an investigation into the Polecat Fire on Friday, June 21, 2024. 

Boise Fire, Boise Police, and the Bureau of Land Management responded to the Polecat Fire which was a grass fire that burned 36 acres and threatened homes at the end of N. Collister Dr., at the Polecat Gulch Trailhead. Thanks to the quick and coordinated response from first responders, the fire was stopped before it led to any injuries or destruction of nearby homes. 

Following an investigation, the fire was determined to be arson and video from the area led police to identify a suspect. Following further investigation, Bryan Grensing was arrested and booked into Ada County Jail on the listed charges. The investigation is ongoing and additional charges are pending. 

Boise Parks and Recreation and Ridge to Rivers announced today that the trails within Polecat Reserve are back open for use following Friday’s fire. Please do not venture off the trails into burned areas for your own safety.
