King Karl's been convicted.
Karl Twilleager, vice president of the local chapter of the Ghost Riders motorcycle club, pleaded guilty Thursday in U.S. District Court in Tacoma to illegally possessing a short-barreled shotgun and explosives.
Twilleager, known as "King Karl" in biker circles, faces as much as 10 years in prison when he's sentenced Dec. 6, although prosecutors and defense attorneys will recommend a 5-year term.
Twilleager, 66 of Spanaway, was arrested in June after federal agents raided his house and a storage unit he rented. The agents were looking for firearms and bomb-making materials, court records show, and they found them.
Agents recovered two sticks of an explosive called Emulsion, blasting caps, rifles, shotguns and pistols. There were a dozen guns in all plus ammunition, records show.
A previous conviction for second-degree murder out of Grant County prohibited Twilleager from owning guns.
Authorities began investigating Twilleager after receiving a tip he planned to blow up Uncle Sam's Bar & Grill on Pacific Avenue in Spanaway.
An informant told investigators Twilleager held a grudge against the business because members of a rival club were known to hang out there.
