Andrew Contreras, a 29-year-old Hispanic man from Aurora, Illinois, was shot and killed on January 12, 2021, on the Route 30 overpass near Route 31 in Montgomery. Officers found Contreras inside a vehicle around 11:30 a.m.; he was transported to a local hospital and pronounced dead shortly after arrival.

The Montgomery Police Department and the Kane County Major Crimes Task Force conducted a nearly two-year investigation. On October 5, 2023, U.S. Marshals arrested Rodolfo Madrigal of Streator, Illinois; he was charged with first-degree murder and attempted murder. Police say Madrigal fired shots from another vehicle, striking Contreras multiple times before fleeing.

The investigation remains open and authorities are asking anyone with information about the shooting or possible additional involvement to contact investigators.
