"Ricin Suspect Released from Jail: Was He Framed?"

"Two sources had earlier confirmed to Fox News that the FBI was looking into the possibility that he might have been framed as part of a grudge against him from someone in his neighborhood. A detention hearing for Paul Kevin Curtis that was scheduled for Tuesday has also been postponed."

ADDED: Let's look back to reports after the arrest, which came when people were very keyed up about murderers/terrorists on the loose after the Boston bombing:

If guilty, Curtis didn't cover his tracks very well. The arrest was based on information gathered "very early on," an official tells The New York Times. Presumably that information includes Curtis' use of his actual initials, KC, in the letter.

In fact, Curtis left enough breadcrumbs that a conservative website, Lady Liberty 1885, apparently fingered Curtis hours before the FBI announced his arrest, just through internet sleuthing. Curtis' Facebook posts include both the sign-off used in the ricin letters to Wicker and Obama — "This is KC and I approve this message" — and, according to Lady Liberty, the same quote: "To see a wrong and not expose it, is to become a silent partner to its continuance."

In retrospect, these clues work as evidence of framing. Take someone's Facebook catchphrases and put them in the letter....
