The District of Columbia could soon hold America’s first murder trial in which a relatively new technology that can identify the location and caliber of gunshots plays a prominent role, officials said.

The ShotSpotter system, which uses global positioning technology to fix where shots were fired, and the characteristics of the weapon, helped D.C. police capture a man accused of killing a landscaper working in Anacostia in October 2006, according to police officials. If the first-degree murder case against Lankward Harrington makes it to trial in October, it will become the first time the company will provide expert testimony in a murder trial, ShotSpotter officials said.
