Two sources had earlier confirmed to Fox News that the FBI was looking into the possibility that Curtis might have been framed as part of a grudge against him from someone in his neighborhood. A detention hearing for Curtis that was scheduled for Tuesday has also been postponed…
Investigators earlier said they hadn't found any ricin in Curtis' house. Agent Brandon Grant said that a search of Curtis' vehicle and house in Corinth, Miss., on Friday did not turn up ricin or ingredients for the poison. A search of Curtis' computers has found no evidence so far that he researched making ricin.
The charging documents, according to Fox, included a quote on his Facebook page that was repeated in the ricin letters (someone let the boys at bureau know there’s no such thing as private on Facebook) as well as a 2007 report from his ex-wife that Curtis was “extremely delusional, anti-government, and felt the government was spying on him with drones."
The Mississippi man faced 15 years in federal prison had he been convicted.
