One explosive device was found inside the bunker and another was located in the PVC pipe negotiators used to communicate with Dykes, the FBI said Tuesday night. Both devices were "disrupted," according to the FBI. The search for hazards is expected to continue through today.
Preliminary investigation reports indicate that Dykes engaged in a firefight with the SWAT agents who made entry, according to the FBI.
Officials were able to insert a high-tech camera into the 6-by-8-foot bunker to monitor Dykes' movements, and they became increasingly concerned that he might act out, a law enforcement source with direct knowledge of the case told ABC News Monday.
FBI special agents were positioned near the entrance of the bunker and negotiators were able to convince Dykes to approach the bunker door. FBI agents used two explosions to gain entry into the bunker. It also appears that Dykes reinforced the bunker against any attempted entry by law enforcement, according to the FBI.
ABC News has learned that Dykes first opened fired on the agents during the bunker raid. Moments later, the agents returned fire, killing Dykes. Read more at ABC News
