ShotSpotter activations indicate gunfire in the city, but no one hurt.
SPRINGFIELD — The city's ShotSpotter acoustic gunfire plotting system activated several times overnight, including one incident on Revere Street in which four, high velocity rifle rounds were fired at a house.
Capt. Trent Duda confirmed that the ShotSpotter system indicated four rounds were fired at approximately 1:10 a.m. near 14 Revere St., and police found several spent shell casings for .223 Remington or 5.56mm military cartridges. The 5.56mm round is used predominently in military-styled weapons, such as the Bushmaster civilian version of the M-16 military assault rifle. The Bushmaster fires the same high velocity cartridge, but is capable of semi-automatic operation. The Bushmaster was used in the Newtown Sandy Hook School shooting.
Police said four rounds struck the home on Revere St.; two rounds hit a porch and two went through a window. There were no apparent injuries.
Police again found shell casings near 926 Worthington Street after the ShotSpotter system indicated gunfire. There were no reported injuries in that incident as well.
The ShotSpotter system uses a group of microphones set up around various parts of the city, and when gunfire is registered, a computer system triangulates the location of the shots. The system is reputed to be accurate to within a matter of several feet.
