A 57-year-old Victorville, California man led a Grand Teton National Park ranger on a fast-moving pursuit on U.S. Highway 26/89/191 north of Moose Junction late Sunday night, and was finally stopped with the aid of spike strips. According to Park Spokesperson Jackie Skaggs, a ranger attempted to stop the vehicle for crossing the centerline several times, but the driver did not yield and increased his speed instead. The park ranger then contacted Teton Interagency Dispatch Center to request back up as she tried to pull over the northbound driver. The driver refused to stop and gradually increased his speed from 40 to 60 mph. The nighttime speed limit on Highway 89 is 45 mph. Two North District rangers responded and they placed road spikes across the highway near Triangle X Ranch. The spike strips were successful in slowing the fleeing vehicle, although the driver continued traveling on flat tires before coming to a stop near Cunningham Cabin nearly one mile beyond the road spikes. While in pursuit, the ranger also saw the driver toss something from the truck window just before the vehicle came to a stop. An additional ranger and drug dog responded to search for the tossed item, which turned out to be a controlled substance. Ronald Lynell Tucker was arrested for interference with agency functions, and charged with several other violations including the operation of a vehicle while under the influence of alcohol or drugs. While Tucker has no current warrants, he has a lengthy criminal history. This marks the second time within a month rangers have had to deploy spike strips to end a chase in the park.
