Sterling Hall bomber Karl Armstrong arrested after state troopers find $800,000+ in his motor home.

The bombing, which killed a man, happened here at the University of Wisconsin in 1970. Armstrong served 7 years in prison and has been free for more than 30 years. According to the court document filed yesterday, Armstrong was stopped for a traffic violation while driving on I-90, and, according to the state trooper, Jose Alvarez, seemed nervous. Alvarez "asked whether Armstrong had any drugs, guns or large amounts of cash, and Armstrong answered no."

Alvarez asked if he could search the motor home, and Armstrong said no.

Armstrong agreed to wait for a police dog to be sent to the scene, but while waiting for the dog Armstrong approached Alvarez and said he had changed his mind and agreed to the search.

Inspecting a bed in the motor home, Alvarez noticed a plywood plank with scratched and tool-marked screws and removed the screws and plank. He found two duffel bags, a brown paper bag and a black cooler pouch. Each contained heat-sealed bags of cash, which was later found to total about $815,000. Investigators who processed the money said it smelled strongly of cannabis.

Armstrong was arrested but denied knowing anything about the money, only that he had $4,000 in traveling money and was returning home to Madison.
