Federal prosecutors have dropped charges against a Mississippi man they accused of sending ricin-laced letters to President Obama and two other public servants, according to a court order obtained by the AP.

Nicaraguan authorities say they have detained Eric Justin Toth, a former teacher at a Washington, D.C., private school accused of producing child pornography.

Back in April 2012, Toth took Osama bin Laden's place on the FBI's Ten Most Wanted list.
