Federal agents arrested a man on Monday suspected of sending letters feared contaminated by the poison ricin to President Obama and a Mississippi senator, according to two officials with knowledge of the case. The New York Times is reporting the suspect was identified as Paul Kevin Curtis of Tupelo, Miss. Curtis also sent a third letter to a Mississippi justice official, the FBI said.  The Washington Post reports he is well known to law enforcement as a frequent letter-writer to lawmakers, according to federal officials.

Now, CNN is reporting, the Clarion-Ledger of Jackson, Mississippi, posted photographs of a man it identified as Paul Kevin Curtis. In one photograph, he is shown under an “Elvis” sign holding a microphone as he appears to be singing. He is wearing a white suit and sporting long sideburns and swept-back hair. A Kevin Curtis Live Facebook page describes him a “Master of Impressions performing ‘Tribute to the Stars’ for audiences of all ages!”
