Who is Paul Kevin Curtis? Man arrested in ricin letter case active on social media

Despite his arrest in connection with poisonous letters posted to President Barack Obama and another senator, Paul Kevin Curtis doesn't seem like the "snail mail" type given his ardent dedication to non-traditional communication platforms like YouTube (where he has his own channel), Facebook (where he posts a lot), and Twitter (ditto). 

The Federal Bureau of Investigation (FBI) arrested Curtis on Wednesday over his believed connection to letters sent to Obama and other US officials that initially tested positive for the deadly poison ricin, reported Reuters. 

The FBI said poisonous letters were addressed to a total of three individuals — a US senator, the White House and a Mississippi justice official,said Reuters.

According to the Associated Press, Curtis was conviced "various parties within the [US] government" were conspiring against him and also thought body parts were being sold by medical facilities on the black market.

Online messages under Curtis' name dating from 1998 to 2000 claim the discovery of a "refrigerator full of dismembered body parts & organs wrapped in plastic in the morgue of the largest non-metropolitan health care organization in the United States of America," said AP. 

Curtis also reportedly had a run-in with Mississippi Senator Roger Wicker, a lawmaker also sent a suspicious letter on Wednesday. 

"I even ran into Roger Wicker several different times while performing at special banquets and fundraisers in northeast, Mississippi but he seemed very nervous while speaking with me and would make a fast exit to the door when I engaged in conversation…" AP quoted Curtis as writing, using the same sign-off reportedly seen on the Obama and Wicker letters: "This is Kevin Curtis & I approve this message."

Wicker remembered the exchange, according to CBS: 

Exact charges against Curtis have not been released. While legal details remain murky, there is much to be gleaned about Curtis on social media.

For example, in this autobiographical YouTube video, Curtis is excited about a new janitor job and mentions jail time: "People were saying, you're not going to find a job, you know, getting out of jail and all," he explains. He also tells viewers he's always been called Kevin instead of Paul ("I don't know why my parents gave me three first names and never even called me by my first one," he says) and talks about being teased in high school. "Kids called me a lot of things." Here's more of his social media activity:
