BELLINGHAM - A Ferndale man was arrested at gunpoint on Interstate 5 Saturday, July 28, after a brief pursuit that topped 100 mph.

A black Ford pickup was reported going over the speed limit northbound about 12:30 p.m. as it crossed into Skagit County, said Washington State Patrol Trooper Keith Leary. The driver was cutting off cars and using the shoulder to pass.

The pickup traveled "a whole county-and-a-half" before troopers could find it, because of unclear and inaccurate information from callers, Leary said.

An officer at a Bellingham onramp spotted the truck at 1:15 p.m. and turned on her cruiser's lights and sirens. She clocked the pickup at 92 mph. The pickup driver accelerated to 102 mph, Leary said, before pulling over about 30 seconds later near the Lakeway exit.

Officers noticed the driver making "furtive movements" in the truck, like he was reaching for a gun or trying to hide contraband, so they ordered him out of the cab and handcuffed him at gunpoint, Leary said.

The truck was impounded pending a search warrant after troopers peered into the windows and saw evidence of drugs and alcohol inside, Leary said.

Heath Garrett Ivy, 28, was arrested on suspicion of being under the influence of both. He's also accused of reckless driving.
