Rockford Police say the new ShotSpotter system has directly led to the arrest of 16 individuals on charges ranging from weapons to fireworks, since it went operational in March.
ShotSpotter technology uses small audio sensors placed throughout the city to triangulate the sound of gunfire and pinpoint the number of shots fired at that location.
The benefit is that it allows officers to respond to a location sometimes before a crime is called in.
ShotSpotter also assists in the recovery of evidence.
As an example, police say ShotSpotter detected shots fired in the 1100 block of 17th Avenue, which led officers to the arrest of 32-year-old Jerry Tilly on October 9th. Tilley faces charges of Unlawful Use of Weapons by a Felon, Unlawful Use of Weapons by a Street Gang Member, and Reckless Discharge of a Firearm.
Police say incidents related to gunfire in Rockford this year are down 18 percent over 2017.
