Man who threatened to bomb Huntley High School sent to prison for battering nurse

A McHenry County man convicted in 2024 of threatening to bomb Huntley High School has been sentenced to three years in prison for the battery of a nurse in McHenry.

Jonathan Franzen, 28, of Woodstock, admitted to a charge of aggravated battery, a Class 3 felony, under a plea deal in which prosecutors dismissed additional counts of criminal sexual abuse with force and misdemeanor disorderly conduct.

Authorities alleged that on Sept. 11, 2025, Franzen “made physical contact of an insulting or provoking nature with ... a nurse,” when he inappropriately touched her between the legs, then made a lewd comment, according to court records.

Franzen is required to serve half his prison time and gets credit for 180 days already spent in county jail. After prison, he will be on six months of mandatory supervised release, according to an order signed by Judge Tiffany Davis.

At the time of battery, Franzen was on pretrial release on retail theft and aggravated battery charges stemming from separate incidents. Those cases were dismissed as part of the negotiated plea last week, records show.

Authorities say Franzen threatened to bomb Huntley High School on Jan. 10, 2020, via the social media app Snapchat, Police ultimately determined he had no means to carry out the threat.

On that case, Franzen was accepted in 2022 into McHenry County’s mental health court, a diversion program that would have kept him from being prosecuted. But he was kicked out after committing several violations; he then pleaded guilty to disorderly conduct and was sentenced to 18 months in prison, court records show.
