Shotspotter: Tracking the sound of crime
TRENTON, NJ — Homicide detectives talk about the first 48, the crucial two-day period immediately following a murder during which their investigation is most likely to find leads that will solve the case.
But even more vital to a police officer are the moments immediately after a shooting has occurred, when getting to a crime scene as soon as possible can save a life or take the shooter into custody.
“A few seconds could mean a matter of life or death for that victim,” said Sgt. Pedro Medina, a spokesman for the city police department. “And the difference between apprehending and not apprehending the suspect.”
A system of acoustic sensors known as ShotSpotter, purchased by the city police department with the help of federal funding, is geared to alert police within seconds of a shooting and get cops to the scene more quickly.
“You can actually smell the gunfire,” Police Director Irving Bradley Jr. said. “That’s how fast you can go there.”
