Wisconsin police told Fox News on Tuesday they were fully aware they could be engaged in a suicide-by-cop showdown if they encounter manhunt suspect Joseph Jakubowski, wanted for stealing guns and mailing a 161-page manifesto to President Trump.
"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." "We haven't had anyone get hurt and we certainly don't want him to get hurt."
In addition, law enforcement officials said they would provide extra security to House Speaker Paul Ryan -- who hails from the city at the center of the search -- and his family.
Jakubowski, 32, disappeared after allegedly stealing 18 firearms from a gun shop in Janesville. His stepfather, Don McLean, and the suspect’s mother told The Associated Press they wanted Jakubowski to give himself up because they “would rather have him alive.”
Also Tuesday, police said Jakubowski may have shaved his head, releasing an image showing the suspect without hair.
Janesville Police Chief David Moore told ABC News' "Good Morning America" the FBI and Bureau of Alcohol, Tobacco, Firearms and Explosives would work with U.S. Capitol police to reduce the threat while protecting Ryan and his family. Janesville is Ryan's hometown.
“Our concerns are with the speaker and his family,” Moore added.
Rock County sheriff’s officials released new photos Monday evening and have received and followed up on hundreds of tips from the public, Fox 6 reported.
Rock County Sheriff Richard Spoden said Jakubowski threatened to attack public officials and schools in his manifesto.
“While we know he had a plan, we don’t know what the endgame is,” David Moore, Janesville police chief said.
More than 150 state and federal law enforcement officers are searching for Jakubowski. The FBI, the U.S. Secret Service, and the Bureau of Alcohol, Tobacco, Firearms and Explosives are involved in this investigation.
The FBI is offering a $10,000 reward for information that leads to the capturing of Jakubowski.
