JANESVILLE - Schools in Janesville and Milton were closed Friday as a massive search continued for a man officials say sent a threatening manifesto to President Donald Trump and is suspected of stealing more than a dozen weapons from a Janesville gun store on Tuesday.

The FBI has offered a $10,000 reward for information leading to Joseph Jakubowski, 32, the Janesville Gazette reported.

The school closures followed '"soft lockdowns" on Thursday when investigators learned from Jakubowski "associates" that unspecified schools were among the targets of his general anger.

The Delavan-Darien School District announced its schools are open Friday, but, "in a general or soft lockdown situation again as a precautionary measure." That generally means classes are in session, but all doors to facilities remain locked.

Delavan-Darien also canceled all in-town after-school activities on Friday.

The Gazette reported that Rock County Sheriff Robert Spoden said more than 150 local, state and federal enforcement officers continue to search for Jakubowski. The wide effort began Thursday morning.

An automatic weapon was reported to be among the many firearms taken in a Tuesday night burglary at Armegeddon Supplies, according to Gazette reports.
