FBI and other federal law enforcement were back in James Everett Dutschke's Tupelo, Miss., neighborhood late Tuesday afternoon combing over his house for more evidence.
This was a short time after an FBI affidavit was unsealed to reveal that items removed from Dutschke's Taekwondo studio tested positive for ricin.
Neighbors told FOX13 News on Wednesday about how a child may have helped tip off the feds.
For some in Tupelo, there is real concern over the future of the shopping center where Dutschke's former Taekwondo school was located.

"I heard they found poison in the plumbing, and I am sure they will have to do a good decontamination if anybody else will ever use it again," said a concerned resident.
"If there is poison in there, they want it torn completely down," said another resident. "They might be getting the health department involved, because it could get airborne."
Word is in Dutschke's neighborhood it was a child, one of their very kids that Dutschke is accused of molesting, that told an FBI agent that Dutschke told her that he had special knowledge of how to make poison.
"I think that it was one of the children that told one of the parents and they told the FBI."
"I've been hearing that the kids are talking about what Mr. Dutschke has been doing as far as making this lethal drug, or this lethal ricin as they call it."
