GRANITE CITY – The Illinois State Police (ISP) is releasing video of an officer involved shooting after an investigation at the request of the Granite City Police Department (GCPD) and Madison County Sheriff’s Office (MCSO).

On August 24, 2026, while speaking with an officer, 40-year-old Ryan N. Cerentano of Granite City, IL displayed a handgun.

After refusing to put the handgun down, Cerentano fled in his vehicle.

At approximately 10:19 a.m., GCPD and MCSO officers responded to the 2000 block of Edison Avenue in Granite City where they found Cerentano armed with a handgun and a long gun, later confirmed to be a replica long gun, on his roof.
