The Mississippi man accused of sending ricin-laced letters to President Barack Obama and other officials has been released from federal custody. 

Paul Kevin Curtis was charged with sending a threatening letter to the president last week after security officials found he had sent poisoned letters to the Obama, a U.S. Senator and a Mississippi judge. 

There are conditions attached to his release, but they are currently sealed. 

Curtis' attorney, Christi McCoy said her client was framed by someone who used phrases Curtis likes to use on social media. He was known for ranting online and posting Internet messages about public figures. 

Meanwhile, the FBI is searching the home of a second Mississippi man in connection with the ricin case. 

Everett Dutschke, the man whose home is being searched, has maintained his innocence and said he doesn't know anything about ricin. 

He shares several similarities with Curtis. Both are musicians, martial artists and members of Mensa, an international society for people with high IQs. In addition, both were known for online ranting.
