Bomb technicians found no more explosive devices at the rural U.S. property of the gunman who shot dead a school bus driver and held a 5-year-old boy captive for nearly a week in a rigged underground bunker, according to AP. Jimmy Lee Dykes was killed Monday during a gunfight when police raided the Alabama bunker and rescued the boy unharmed, officials said. FBI spokesman Jason Pack said his body was removed Wednesday night. An autopsy was planned Thursday, and the FBI said teams had already begun sifting the crime scene. The FBI said after the raid that the 65-year-old Dykes had planted one explosive artifact in a ventilation pipe used by negotiators to communicate with him in his bunker. The agency said a second device was found in the bunker. Both were safely removed. FBI Special Agent Paul Bresson said in an email late Wednesday that technicians had "completed their work and cleared the crime scene." "No additional devices were found," he added. -- SPA
