Alton Man Faces Arson Charge Following Belle Street Apartment Fire
ALTON – A man from Alton remains in custody after breaking into, stealing from, then setting fire to an occupied apartment building on Belle Street. Zachary S. Montague, 32, of Alton, was charged on June 25, 2025 with a Class X felony count of aggravated arson and a Class 2 felony count of burglary. Montague is accused of burglarizing and intentionally setting fire to a multi-family residential apartment building in the 3200 block of Belle Street, which he knew or reasonably should have known was occupied on March 27, 2025. According to the state’s petition to deny Montague’s pretrial release, Montague was seen on surveillance footage entering the apartment building at approximately 5:30 p.m. and leaving at 5:41 p.m. with stolen property. Smoke was seen coming from the building six minutes later, and a K-9 unit alerted to accelerants at the fire scene. “The Illinois State Fire Marshal determined the fire was incendiary (intentionally set by human action),”
