The men were questioned about two months ago, around Christmas. Gray said that to protect the integrity of the investigation, he could not comment further. He stressed that the investigation is “open and continuing.”

CBN News also spoke to a Department of Homeland Security official with knowledge of the investigation who wished to remain anonymous. The official confirmed that the investigation was ongoing and said that someone in the Lima 09 program overheard five Muslim colleagues talking about poisoning food at the base. The person then reported the men, who were brought in for questioning.

The DHS official stressed that after the terrorist massacre at Fort Hood, the Army is taking a zero tolerance policy towards any potential threatening statements and is now extremely sensitive about any allegations in that regard.
