Cook County man charged with shooting person trying to break up fight

A suburban Cook County man was arrested and charged for allegedly shooting another man who was attempting to break up a fight that the suspect was involved in.

On March 15, around 6:30 p.m., Palatine police responded to the 1900 block of Green Lane North for an unknown medical problem. After arriving at the scene, officers discovered a victim suffering from an apparent gunshot wound.

The victim was transported to Luther General Hospital for treatment, and officers flooded the area to search for the gunman after they received a description of the suspect who fled the crime scene.

During the search, police learned the suspect tried to enter an occupied vehicle that was in a parking lot in the 1100 block of E. Dundee Road.

The victim who was in the vehicle told police which direction the suspect fled in, and shortly after the suspect was taken into custody.


Police say the gunman was identified as 27-year-old Hector D. Gamboa-Montalvo, a resident of Palatine.
