Police to fire guns Wednesday night in Montbello to test ShotSpotter system

DENVER — Police will test the expansion of their ShotSpotter system in the Montbello neighborhood on Wednesday night.

The ShotSpotter system has been in use in east Denver for the past year. So far, the Denver Police Department said it has detected about 450 alerts and led to 30 arrests.

The live-fire exercise will happen between 8 p.m. and midnight. The live gunfire tests will be followed by sound detection validation by ShotSpotter.

“The ShotSpotter system uses a network of acoustic sensors to detect when a gun is fired and then precisely and quickly pinpoints the location of the gunfire,” police said in a news release. “In less than a minute, ShotSpotter notifies 911 dispatchers of the incidents.”

Police said a bullet trap will be used to make sure the public is not in harm’s way. No bullets will be fired into the air or ground.

The exact location of the ShotSpotter devices are not publicly disclosed “to maintain the integrity of the program,” police said.
