This past weekend, Brockton Police responded to a ShotSpotter GLS alert and nabbed two suspects, each with multiple warrants. A 9mm handgun was also recovered. This is a prime example of  good policework and technology making our streets safer.

Way to go Brockton Police!


BROCKTON —The city’s police gang unit made two weekend arrests, thanks to the department’s gunshot-detection system, police say.

Police early Saturday arrested Jerry Fernandes-Dasilva, 20, of 177 Bowdoin St., Boston, and charged him with unlawful carrying of a firearm, unlawful possession of ammunition, discharging a firearm within 500 feet of a dwelling, receiving stolen property, two default warrants and one charge of unlawful possession of a large-capacity feeding device (magazine).

About 2:39 a.m. Saturday, police said their “ShotSpotter” system picked up three gunshots in the area of 33 Dover St.

People are known to throw after-hours parties in an old factory near that address, said police Lt. Paul Bonanca.

Police say they observed someone ducking down in a parking lot and placing a firearm above the tire of Ford F-150.

Authorities arrested Fernandes-Dasilva and recovered 9mm handgun with five rounds. Police also found three shell casings in the area.

Police arrested the second man nearby. Herico Andrade, 27, of 63 Tremont St., Brockton, was arrested on three warrants, according to police.

Brockton police have used the gunshot-detection system since early 2010, Bonanca said.

The ShotSpotter system picks up the sound of gunfire using a series of sensors and, through an acoustic-based global positioning system, sends the location to police immediately. It can also tell how many guns have been fired.
