At 5:20 a.m. Monday, a caller contacted the Juneau County Communications Center and said Joseph A. Jakubowski may have been spotted in a New Lisbon business early Monday morning, according to the Juneau County Sheriff's Department.
Jakubowski is accused of breaking into a gun store last week, stealing several assault weapons and mailing an anti-religious manifesto to President Trump.
Spoden said that a friend of the suspect told authorities that Jakubowski was angered by national politics and "recently verbalized a plan to steal guns and use them in an unspecified attack". Police increased patrols near Janesville churches on Sunday, although investigators said there was no specific threat.
Bethlehem Lutheran in Sun Prairie, less than 50 miles north of Janesville, canceled services after a man who was believed to resemble Jakubowski visited the church on Thursday.
Law enforcement officials searching for a Wisconsin man suspected of stealing a large number of firearms and threatening an attack are getting more help from federal investigators as they follow hundreds of leads in search of the man.
On Tuesday police found Jakubowski's vehicle on fire not far from where the gun store theft took place, according to NBC News.
About 150 local, state and federal officials Sunday entered their third day of searching for Jakubowski, who is considered armed and risky.
The FBI also released an enhanced photo Tuesday of Jakubowski that shows what he might look like with a shaved head and without facial hair. Schools were notified based on the information. Authorities believe he is armed and risky, and traveling with a bulletproof vest and helmet.
The individual also conveyed that Jakubowski had written a lengthy manifesto airing his grievances with the government and that he had mailed the 161 page manifesto to President Trump. Police believe Jakubowski torched the truck.

The FBI is offering a $10,000 reward for information leading to the capture of Jakubowski, who is also in possession of body armor and should be considered armed and unsafe.
He has one felony conviction for attempting to steal a gun from a police officer in 2008, and a history of misdemeanors. A short time later, his auto was found burned just a short distance from there.
