LOS ANGELES - Gunfire detection technology helped police arrest the suspect in a shooting spree in which three people were killed on Tuesday in Fresno, California.

The ShotSpotter is a system of sensors, which "listen" to shots and immediately identify the location, number of shots, and types of weapons within its area of coverage.

The sensors, installed about 9 meters above street level and 420 meters apart, immediately provided accurate location and helped police arrested the suspect at the scene.
