PLAINFIELD - Plainfield officials say they are fighting back against a recent spike in violent crimes in the area.

Mayor Sharon Robinson-Briggs and Public Safety Director Martin Hellwig spoke to their critics today who think they have not done enough to curb growing violence. They say they are putting more police patrols on the street, focusing on more violent areas, and introducing a radar system that would detect when and where a gunshot has been fired.

Police say there were 24 murders in Plainfield between 2009 and 2011. The latest was last Thursday, when a 54-year-old Hispanic man was shot to death.

No arrests have been made in that incident.
