UPDATE TWO: The FBI responded to ABC57 with the following statement:

"The Department of Justice policy is to neither confirm nor deny if we are conducting an investigation. As a general matter, allegations of criminal conduct are reviewed by the FBI for their merit, but such a review does not necessarily result in the opening of a full investigation."

UPDATE: Berrien County Sheriff Chuck Heit reports the FBI activity in the county Wednesday involved the execution of 14 search warrants.

This resulted in three people arrested for federal charges and one person on state charges.

A total of five guns were recovered, one of which was stolen.
