FOND DU LAC, WI (WTAQ-WLUK) — Caiden Stachowicz was convicted Monday of setting fire to U.S. Rep. Glenn Grothman’s Fond du Lac office.
Stachowicz, 20, pleaded no contest to arson. Two other counts were dismissed. Sentencing is scheduled for March 5.
According to the criminal complaint, Stachowicz admitted to attempting to break into the congressional office on Jan. 19 in order to set the fire. When that didn’t work, he wanted to pour gasoline outside the building from the back to the front. Strong winds and fear of injuring himself led Stachowicz to simply light an electrical box in the back of the building on fire, the complaint says.
Prosecutors say Stachowicz was upset over Grothman’s vote in favor of the short-lived ban on TikTok.
Stachowicz was arrested shortly after crews extinguished the fire at the office, located at a strip mall. No one was injured during the fire, but Grothman’s office sustained damage.
Prosecutors originally also charged him with making terrorist threats, but because there was no threat made before the acts, a judge dismissed that count.
Grothman is a Republican who represents Wisconsin’s 6th congressional district. He was first elected to his seat in 2014.
