FRESNO, Calif. (AP) " Acoustic sensors mounted on lampposts and telephone poles picked up the crack of gunfire and rapidly enabled police to zero in on where it was coming from. "He was in custody within 4 minutes and 13 seconds," Dyer said Wednesday at a news conference where he played audio clips of the ShotSpotter technology. First developed two decades ago, ShotSpotter technology has been used widely since 2011 in U.S. cities. The Fresno rampage is one of the more serious crimes in which it played a vital role. Police say Muhammad randomly targeted white men he encountered in a tree-lined Fresno neighborhood, firing 17 rounds within a few minutes before running out of ammunition, police said.
