You know, what with the Boston Marathon bombing last week, we almost forgot about the other "terrorist" — the guy who sent ricin in the mail to his Senator and President Obama.

Paul Kevin Curtis was arrested last Wednesday.

Except… hmmmm… there's breaking news that they released him today, the day of his first hearing before the court:

A federal official says the man charged with sending poison letters to President Barack Obama, a U.S. senator and a Mississippi judge has been released from jail.

Jeff Woodfin, chief deputy with the U.S. Marshals Service in Oxford, Miss., says Paul Kevin Curtis has been released from custody.

Woodfin says he doesn’t know if there were any conditions on the release.

The development comes hours after officials canceled a detention and preliminary hearing on Tuesday.

Curtis was arrested Wednesday at his house in Corinth, Miss., and charged with sending ricin-laced letters to Obama, Sen. Roger Wicker and a Lee County, Miss., judge.

Through an attorney, the 45-year-old Curtis has said he is innocent.

Law enforcement screwup?

UPDATE: Twitter is alive with rumors that there was another Ricin attack at an Air Force Base today.  So maybe Curtis' claims of innocence were right after all.
