The Alabama bunker in which a young boy was held hostage for a week also had homemade bombs.
CBS News tweeted that Jimmy Lee Dykes, the man who took the 5-year-old hostage, had stored homemade bombs in his underground bunker.
Dykes was killed when authorities invaded the bunker Monday in southeastern Alabama. The 5-year-old was successfully freed.
The boy's grandmother told the Associated Press she fears the crisis will stay with the child for the rest of his life.
"We know he's OK physically, but we don't know how he is mentally," Betty Jean Ransbottom said.
Dykes took the child off a school bus after he shot and killed the driver.
After days of unsuccessful negotiations, authorities stormed the compound.
"He always said he'd never be taken alive," an acquaintance of Dykes, Roger Arnold told the AP. "I knew he'd never come out of there."
