The Rock County Sheriff's Office said Wednesday that more than 700 tips have been received so far. "It has been a little frustrating that we have not found this individual yet, and we'd sure like to see this situation resolved".
Sheriff Robert Spoden has said Jakubowski threatened to attack schools and public officials in the 161-page manifesto that he mailed to President Donald Trump.
Tips continue to flood the Rock County, Wisconsin Sheriff's Office on the possible whereabouts of fugitive Joseph Jakubowski.
Authorities believe this manifesto was written by Joseph Jakubowski, a man who is now the subject of a national manhunt.
Authorities also had a copy of the manifesto after it was turned over by an associate of Jakubowski.
Even though Jakubowski wrote in his manifesto that religion, as a whole, is bad and is used for financial gain and to keep people enslaved and alter their thinking, Spoden said Jakubowski doesn't make any specific threats to churches in it.
In the 35 pages obtained exclusively by NBC5 News, Jakubowski refers to health insurance, taxes and religion as examples of the government trying to brainwash its citizens. They say Jakubowski has survivalist equipment but he is not a survivalist.
A law enforcement official close to the investigation confirmed the portion of manifesto as authentic, according to the affiliate. "But I was very shocked when I saw the news reports", said a Sussex resident.

It raises the grim prospect of more marketers taking advantage of the growing number of voice activated devices in people's homes. Google Home, if placed close to the TV, will light up and rattle off a Wikipedia definition of what is in the 100% beef Whopper.
Jakubowski is considered "armed and dangerous" and was in possession of a bullet-proof vest and helmet, police have said.
After allegedly breaking into Armageddon Supplies gun store and taking as many as 16 high-end firearms, Jakubowski writes that he had no choice. Direct sightings of Jakubowski should be called into 911 immediately.
Last week, authorities released a video that they believe was posted by the suspect, showing him mailing the manifesto to Trump. "He was anti-government, and he certainly had his concerns on the federal government and (was) anti-religion".
But investigators do not have a copy of the document that WTMJ TV says it has, said Cmdr.
We also learn from his writings that he's an artist but he claims that government regulations destroyed his passion.
As of Wednesday night, approximately 700 tips have been received, and investigators are now pursuing about 130 tips.
The FBI Milwaukee Division announced Tuesday afternoon the reward is now $20,000 dollars, for information leading to the successful location of Joseph Jakubowski, 32.
