It was filled with barbs directed at officials from all levels of government, Rock County Sheriff Robert Spoden said last week.
Public perception of the threat to safety represented by the fugitive, Joseph A. Jakubowski, 32, has grown since the Rock County Sheriff's Department released details on his crimes and philosophy.
Jakubowski is believed to have stolen 16 high-end guns from a Janesville store earlier this week.
Police in Sun Prairie said a sighting of a suspicious person outside a Lutheran church Thursday was not Jakubowski. More than 150 federal, state, and local police officers are searching for Jakubowski in Wisconsin and out-of-state leads are also being followed up.
About 30 minutes after the burglary, police found Jakubowski's auto ablaze on a nearby street along with evidence of arson, according to Cmdr.
"I'm confident that if that were the case, we are going to do everything we can to keep our community safe and keep our officers safe", Rock County Sheriff Richard Spoden said on "America's News HQ".
Jakubowski has had several run-ins with law enforcement over the years.
They say he also mailed his anti-religious and anti-government manifesto to President Trump.
Authorities alerted school districts to notify them about Jakubowski. Police believe Jakubowski torched the truck. Back in 2008, he attempted to steal a gun from a police officer and has committed more misdemeanors in the past.
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 risky.
Jakubowski is described as 5ft 10 inches tall and weighs around 200lbs. They discovered that the burned auto belonged to Jabukowski, it was found near the gun shop that was robbed.
Jakubowski allegedly posted a video to his Facebook page that showed him mailing the manifesto to Trump.
