[2][3][4] Haney was found dead with a gunshot wound in 2020,[3][4] in what was officially ruled a suicide two years later amid conspiracy theories that he had been murdered.
[5][6] Haney was a founding member of the DHS in 2003, and later a terrorism analyst at the National Targeting Center (NTC).
[7] He wrote in 2016 that he was ordered by the DHS in 2009 to "scrub" several hundred records of individuals tied to designated Islamist terror groups like Hamas from the federal database Treasury Enforcement Communications System (TECS).
[8] He published a book titled See Something, Say Nothing: A Homeland Security Officer Exposes the Government's Submission to Jihad the same year, which alleged a cover-up of Islamic terrorist activity by the Obama administration.
[5] His death generated widespread right-wing conspiracy theories promoted by among others Rep. Steve King that he had been murdered by the "deep state", allegedly "because of all he knew of Islamic terrorist coverups," but it was officially ruled a suicide two years later in 2022 after the Amador County Sheriff's Office had brought in Federal Bureau of Investigation (FBI) crime scene investigators and other analysts to assist with the investigation.
