A Mississippi man accused of sending at least two ricin-laced letters to President Obama and Sen. Roger Wicker (R-Miss.) has been released from jail, reports WREG .
Kevin Curtis , an Elvis impersonator, was facing federal charges in the cases. On Monday, the FBI said a search of Curtis' home revealed no traces of ricin. Curtis' relatives told WREG that investigators found a fingerprint on one of the letters that points to someone else.
