Ghost guns have been seized in Operation Casper across Putnam and Westchester Counties.  More than 100 weapons were seized and 11 arrests made following a six-month multi-agency investigation into ghost guns and other illegal firearms in Putnam and Westchester Counties. Search warrants were executed at eight locations in Putnam and Westchester by investigators from County, local and federal law enforcement agencies. Rifles, handguns, and high-capacity drum magazines were seized. Some of the weapons lacked a serial number, making them so-called ghost guns, and other weapons had defaced serial numbers. Several silencers, ballistic vests, counterfeit police shields and quantities of ammunition were also seized in the probe, dubbed Operation Casper. The investigation was launched in June 2021 with the creation of a task force to address an influx of ghost guns and other illegal firearms into the region.  The multi-agency Real Time Crime Center was tasked with finding innovative ways to reduce gun crimes and prevent violence.
