JANESVILLE/DARLINGTON - Authorities are stepping up patrols around southern Wisconsin churches as a precaution as they search for a man suspected of stealing firearms from a gun store after threatening to carry out an unspecified attack. The Rock County Sheriff's Office says 32-year-old Joseph Jakubowski expressed anti-religious views in a 161-page manifesto he sent to the White House. Police were increasing patrols near Janesville churches Sunday, although investigators say there is no specific threat.
