Nineteen-year-old Matthew Williams, 18-year-old Jason Straw and 19-year-old Ryan Bussey, all of South Beloit, along with Jacob Darling of Capron were charged with burglary to a vehicle.
Police were called to the 5100 block of Pierce Lane around 2:00 a.m. Monday morning. A witness reported seeing a suspicious vehicle with its occupants checking out parked cars.
During a traffic stop a short time later, officers were able to connect the suspicious behavior with criminal activity in the area.
Winnebago County sheriff's detectives were called to help in the investigation and have now charged Williams and Straw with additional burglaries.
