From the State’s Attorne:
WISCONSIN BROTHERS BOTH SENTENCED TO NINE YEARS IN PRISON FOR FIRING GUN AT HOME IN HARVARD
McHenry County State’s Attorney Randi Freese announces that Miguel Mercardo, 26, and Roberto Mercado, 22, both of Walworth, Wisconsin, were each sentenced to nine years in the Illinois Department of Corrections after each pled guilty to the offense of Aggravated Discharge of a Firearm, a class 1 felony.
Truth-in-Sentencing will require that the Mercado brothers serve a minimum of 85% of their prison sentences.
On March 31, 2025, at just before 10 pm, officers from the Harvard Police Department were dispatched to the 1000 block of Dewey Street in Harvard after receiving a report of shots fired at a residence and a vehicle, with no lights on, speeding away.

Minutes later, officers located a vehicle matching the description just a few blocks from the scene, with the Mercado brothers inside.

A search of the vehicle revealed several spent .22 caliber casings and several loose live .22 caliber rounds within the passenger area of the vehicle.
Inside the glove box, officers located 240 additional live .22 caliber rounds as well as a fully loaded .22 caliber semi-automatic Beretta M9 .22 LR firearm.
Forensic testing revealed that the spent shell casing from the street outside the residence was fired from the Beretta found in the vehicle.
During the investigation, Miguel Mercado admitted to firing at least three rounds at the Harvard home.
State’s Attorney Freese commends the Harvard Police Department officers for their swift and immediate actions that resulted in the apprehension of the Mercados.
“We are especially thankful to these officers for the quick arrests made preventing further danger to the public. Thankfully, nobody was injured, and justice has been served.” Freese stated.
This case was successfully prosecuted by Special Prosecutor William Bruce.
