Netflix's "The Kings of Tupelo" explains why James Everett Duchtske tried to assassinate Barack Obama with ricin letters in 2013.

The three-part docuseries dives into every wild moment from an Obama assassination attempt to an elephant shot in drive-by, Elvis impersonators, and more.

The man at the center of it all, Paul Kevin Curtis, an Elvis impersonator, was also accused of sending poisonous letters to President Obama and was arrested for it. However, the police didn't have enough evidence, and he was released. It was later revealed that he was framed by a man he had a long-standing feud with.
