More info and a name change:

The FBI has arrested a Mississippi man, Paul Kevin Curtis, in connection with letters laced with ricin that were sent to Sen. Roger Wicker and President Barack Obama.
Federal authorities were in Tupelo on Wednesday investigating the letters. Both letters were signed: "I am KC and I approve this message."
Federal officials had originally identified the man as Kenneth Curtis. They have not confirmed if "Kenneth" is an alias.
Curtis, believed to be 45, is from Corinth.
Agents with the Secret Service and the FBI used the Lee County Sheriff's Department as a staging area for their investigation. Lee County Sheriff Jim Johnson said a press conference is scheduled for 9 p.m.
The letter, received by Wicker's office on Tuesday, had a Memphis postmark and no return address, Senate Sergeant at Arms Terrance Gainer wrote in an e-mail to senators and aides. Tupelo's mail is routed through Memphis.
An FBI spokesperson would not confirm or deny their involvement in any investigation in Tupelo.

Officials have said they don't have any reason to believe the ricin letters were in any way linked to Monday's bombings at the Boston Marathon.
The ricin was confirmed by preliminary tests on Tuesday. On Wednesday, Obama received a similar letter, and once again, preliminary tests showed there was ricin in it.
Ricin is a highly toxic substance derived from castor beans. As little as 500 micrograms can kill an adult. There is no specific test for exposure to it, and no antidote once exposed.
An FBI bulletin stated that both letters, postmarked April 8, included the identical phrase: "to see a wrong and not expose it, is to become a silent partner to its continuance."
Wicker, a Pontotoc native who has an office in Tupelo, serves in the Senate as deputy whip and on the the Armed Services, Budget, Commerce, Environment and Public Works, and Joint Economic Committees. He has been a middle-of-the-road senator in the Republican Conference, ranking as the 27th most conservative member of the upper chamber, according to the National Journal. He is known to be conservative on most social issues.
Wicker has stood firmly against Obama's health-care law. He is a recipient of an A+ rating from the National Rifle Association, though he was one of 16 Republican senators who last week stepped over party lines with his party to vote in favor of beginning the debate on a gun-control bill.
There was some speculation that Wicker's vote may have been the reason he was the recipient of the letter, but the postmark was three days before the vote took place.
Wicker's vote brought ire from conservatives all over the country, with postings shared on social media calling for his removal from office. Wicker responded to those with a statement on his own Facebook. Wednesday, however, he voted against an amendment offered by Sens. Joe Manchin (D-W.Va.) and Pat Toomey (R-Pa.) to extend background checks to firearm sales at gun shows and online.
Failing to meet a 60-vote threshold, the amendment was defeated by a vote of 54-46.
In 2003, a ricin-laced letter was sent to the White House and intercepted at a processing facility. Another was discovered with no address in South Carolina. A February 2004 incident at the Dirksen Senate Office Building where a letter to Tennessee Sen. Bill Frist was found was initially connected to the 2003 letters as well.
A week after the 9/11 attacks, several letters containing anthrax spores were mailed over the course of several weeks to several news media offices and two Democratic U.S. Senators, killing five people and infecting 17 others. The FBI would later call the ensuing investigation "one of the largest and most complex in the history of law enforcement."
