UNDATED (CNN) -- An Alabama boy held hostage for six days is celebrating a birthday. Ethan is 6-years-old Wednesday. Meantime, authorities continue to search the underground bunker where he was held for more bombs.
The FBI found two in and around the bunker Tuesday. The kidnapper, Jimmy Lee Dykes, died in the raid to rescue Ethan.
The FBI has released new pictures on the set-up of the bunker and just how far Dykes went to keep authorities away.
Four feet below the spot is the bunker where Jimmy Lee Dykes held 5-year old Ethan hostage for a week. Dykes told agents to use a pipe communicate. Now know why he made that request. A day after the raid, bomb technicians found an explosive inside that pipe and a second explosive inside the bunker.
Jimmy Davis Jr. is a neighbor. He saw the set-up in its early stages. He says, "It was covered up with two sheets of plywood and nailed together with hinges and stuff as a door to open to it."
Authorities say Dykes had reinforced the bunker to keep them out, but they were inside watching. Sources tell CNN the hostage rescue team snuck in a tiny camera. Special Agent Steve Richardson says, "Mr. Dykes was observed holding a gun. At this point, FBI agents, fearing the child was in imminent danger, entered the bunker and rescued the child."
Brian Martin lives near the scene and says, "I heard a big boom and then I heard, I believe I heard rifle shots."
Sources tell CNN what Martin heard was a diversion. Agents rushed in, Dykes shot at them but in the end he was killed and Ethan was rescued.
A nightly prayer vigil became a celebration of Ethan's rescue and his sixth birthday.
April McDaniel is a local police officer. She's also a mother. She started a Facebook campaign to collect birthday cards for Ethan. Thousands have responded. She says, "I just wish I could be there to see his little face light up when he sees all the response and how many people care and love about him."
After a tumultuous week, Ethan is home from the hospital to celebrate and heal.
