Alabama hostage taker died 'in firefight' 6 February 2013 Last updated at 02:36 The Alabama man who held a 5-year-old hostage in an underground bunker for nearly a week was killed during a firefight with officials, the FBI says. FBI Agent Jason Pack said that Jimmy Lee Dykes "reinforced the bunker" and that two explosive devices were found. Dykes abducted the boy, named Ethan, last Tuesday after shooting dead the driver of his school bus. The boy was unharmed but taken to hospital after officials raided the bunker on Monday. His grandmother told the Associated Press that, while he was fine physically, she feared the ordeal could stay with him. "For the first time in almost a week, I woke up this morning to the most beautiful sight... my sweet boy," Betty Jean Ransbottom said, "I can't describe how incredible it is to hold him again." The stand-off began last Tuesday after the 66-year-old bus driver, Charles Albert Poland, tried to stop Dykes boarding the bus and seizing two young boys, aged six and eight. Witnesses said Dykes fired four shots, killing the driver, and taking the five-year-old at random. Charles Poland's funeral was held on Sunday, with a local school system hailing him as a hero. During the six-day standoff, negotiators talked to Dykes and delivered medication and toys to the boy through a 4in (10cm) ventilation pipe. Mr Pack said that officials found an explosive device inside the pipe, as well as another device inside the bunker. At an earlier news conference, the FBI said that officials had decided to raid the bunker after negotiations deteriorated and Dykes was seen holding a gun.
