Paul Kevin Curtis has been arrested and charged with making threats against the president and sending letters threatening to injure other persons. Relatives, who call him a 'super entertainer,' are shocked.
According to the FBI, a Mississippi man was arrested for sending possibly poisonous letters to President Barack Obama and Senator Roger Wicker. There were other reports of mysterious packages in Senate office buildings and in senators' offices in their home states. Authorities are continuing to investigate the suspicious materials.
The interception of the letters appears to demonstrate the effectiveness of security protocols put into place after the anthrax attacks in 2001. The letter that already tested positive for ricin is undergoing further analysis.
