Missoula County Sheriff’s Deputies are searching for Randy Harris, who led authorities on a dangerous vehicle chase in downtown Missoula Monday evening. At about 5:30 pm, Harris and another unidentified man refused to yield to police resulting in a short pursuit in the downtown area. The chase was halted due to concerns for public safety. The vehicle is a black 2000 model Ford Explorer with MT license plate number 5-23220-a. Harris has threatened to shoot it out with law enforcement rather than be taken into custody, and should be considered extremely dangerous. He is wanted for breaking his probation on drug charges in Helena.
