Joseph Jakubowski mailing manifesto to President Trump

The 161-page manifesto is part of the reason for the intense search for Joseph Jakubowski, which reportedly contains threats to public officials and police.

The Rock County Sheriff's Office says in a statement that the Armageddon Gun Shop was burglarized of a "large quantity" of weapons Tuesday night.

The FBI in Milwaukee said it's offering a $10,000 reward for information leading to the arrest of Jakubowski.

Authorities allege Jakubowski had threatened to steal weapons and use them against public officials or at an unspecified school. Elworthy stressed that the concern was not related to the Janesville gun store robbery and manhunt. Jakubowski is considered armed and extremely risky. Authorities said the vehicle was registered to Jakubowski and that the burglary and arson incidents appeared to be connect. Blackhawk Technical College canceled classes, and the University of Wisconsin-Rock County campus is closed on Friday. Jakubowski included a long laundry list of what he believed were injustices by law enforcement and govermental departments and expressed his dislike of any authority figures, Spoden said.

Joseph Jakubowski is no stranger to law enforcement.

"We are doing that as the result of the recommendation of law enforcement", Henning said.

Fox6Now reported that on Thursday several schools in the Janesville area initiated "soft lockdowns".

He said the cooperation among law enforcement agencies in this case has been impressive and it has involved 150 state, local and federal law enforcement officials who have run down 65 leads in the case. The lockdown comes after authorities received word of Jakubowski threatening local schools.

If you have information on the crime or the person in this photo, please call Janesville Police at 755-3100. "Most of his activities have been anger-driven either toward the officers or toward other individuals, but not the antigovernment rhetoric, and that is a new piece to this investigation".
