Jacubowski stole 16 high-caliber rifles and handguns from a Wisconsin gun store after threatening President Trump.

NBC News reported:

Wisconsin police were widening their hunt Saturday for a 32-year-old man who allegedly burglarized a gun store after mailing an anti-government manifesto to President Donald Trump. Joseph Jakubowski has been on the run since Tuesday, when police say he broke into the Armageddon Gun Shop in Janesville, south of Madison, and stole 16 high-caliber rifles and handguns. He is believed to be armed and dangerous, and traveling with a bulletproof vest and helmet, according to authorities. At a news conference Friday, Rock County Sheriff Robert Spoden said Jakubowski had been highly agitated by national politics recently and had confessed to friends that he had plans to steal guns and conduct an “unspecified attack.” Janesville Police Chief David Moore said his department has also had multiple run-ins with Jakubowski over the years.
