A Ridgefield man has pleaded not guilty to four felony weapon charges after police say illegal firearm suppressors and gun components were seized from his Main Street apartment. 32 year old Patrick Doty was arrested January 2 following a September incident that began with a medical emergency call. Police say they recovered metal and 3D printed silencers, unserialized firearm parts, and evidence of ongoing 3D printing activity. Doty is due back in court February 23.
