ROCK COUNTY -- A man suspected of burglary at a Wisconsin gun shop is on the run after allegedly mailing a manifesto to President Donald Trump, detailing his grievances against the government, and threatening to use the stolen firearms against schools and public officials. Officials with the Rock County Sheriff's Office said Sunday night, as of 9:30 p.m., Joseph Jakubowski remains at large, "despite extensive efforts" to locate and capture him.
In their latest update, officials said Sunday night "contact has been made with area school districts to advise that Jakubowski remains at large, so they can make a determination regarding precautionary measures." Sheriff's officials noted that they are "not aware of any threat towards a specific school or school district," and said "fortunately, many Rock County schools are on spring break this week."
Jakubowski, 32, allegedly robbed the gun shop in Janesville on Tuesday, April 4th the Rock County Sheriff's Office said.
"A large quantity of high-end handguns and rifles were stolen and the suspect fled the scene," authorities said in a statement.
About 30 minutes after the burglary, police found Jakubowski's car ablaze on a nearby street along with evidence of arson, according to Cmdr. Troy Knudson.
The suspect was nowhere to be found.
Some 150 local, state and federal law enforcement officers were actively searching for Jakubowski on Sunday, April 9th, the Rock County Sheriff's Office said.
This, as residents in the Janesville area adjust to a "new normal."
"I think it's crazy. It's ridiculous," Brittany Mulryan said. "I've been stuck in my house with my son. I don't take him out because of this nonsense that's going on."
Sunday was the first time Mulryan took her four-year-old son Michael outside.
"Try to continue doing life as normal. I would hope it would be resolved soon," Cameron Rebarchek, who has been following the news on his laptop said.
Authorities said the same day he allegedly robbed the gun shop, Jakubowski sent a 161-page manifesto to Trump.
Knudson said the White House has received the manifesto. CNN has contacted the White House for comment.
It "includes grievances against government and personal angst toward anyone or anything other than natural law or rule," the Rock County Sheriff's Office said.
Authorities released a cellphone video that appears to show Jakubowski at a post office, mailing a bulky envelope addressed to President Trump at the White House. The video, which Knudson said was posted on social media, shows Jakubowski's name and a Janesville return address on the envelope.
Knudson declined to confirm what social media platform the video was on.
Investigators said they analyzed the manifesto and discovered anti-religious views. As a result, they beefed up patrols at churches and places of worship, but emphasized that there is no specific threat to any religious group.
Services at Bethlehem Lutheran Church in Sun Prairie, near Madison, were canceled Sunday after a man who looked like Jakubowski was spotted near the church on Thursday, the Rock County Sheriff's Office said. Sun Prairie police later said the man was NOT Jakubowski.
Jakubowski was last seen at a gas station on Milton Avenue, on Tuesday -- where he bought cigarettes and Mountain Dew.
In his manifesto, Jakubowski also threatened to steal weapons and use them against public officials or schools, prompting officials to shut down the Janesville School District on Friday, April 7th. Schools in the Janesville School District will remain closed through the 18th due to spring break.
Jakubowski is considered armed and dangerous. Anyone who sees him should call 911 instead of approaching him, Knudson said.
The FBI has offered a $10,000 reward for information leading to his arrest.
"All local, state and federal agencies continue to be involved in this search and additional resources have come in from Chicago and Minneapolis/St. Paul Minnesota," the Rock County Sheriff's Office said.
In their latest update Sunday night, Rock County Sheriff's officials said they're bringing in SWEPT, the Southern Wisconsin Emergency Preparedness Team, which is a non-profit organization that provides support services to law enforcement. This group will be handling the coordination of food and other supplies for investigators as this manhunt continues.
