Samples of the confiscated chemicals will be sent to an ATF lab, Ham said, and the remainder of the chemicals will be stored in a secure location or destroyed.

At the end of the search, Ham said, agents were to turn the home back over to its owner.

Ham said any additional charges resulting from the search would be up to the U.S. Attorney’s Office. An official at the U.S. Attorney’s Office declined to comment, citing the ongoing investigation.

ATF agents were assisted by Nebraska State Patrol troopers, members of the Omaha police bomb squad and Ralston police and firefighters, Ham said.

Nearly a decade ago, the Belmont house was where a commercial-grade shell was set off. It landed next door in a pool where children were swimming, critically injuring a 13-year-old boy.

Belmont was charged with a misdemeanor and sentenced to 15 days in jail and a year of probation.
