Ted Kaczynski, the serial mail bomber known as the “Unabomber” whose deadly spree lasted nearly two decades, wants to tell his story, Fox8 reported.

Kaczynski, whose infamous 35,000-word anarchist manifesto called for a worldwide revolution against modern society, penned a letter to New Yorker writer Lawrence Wright because he says he is “ready to speak to someone in the media.”

“In order to determine who will get the interview, I am asking you to write me back affirming that you understand that I am not mentally ill as my brother, Dave, would have you believe,” he wrote.

David Kaczynski helped investigators identify Ted as the “Unabomber,” ending a 16-bomb spree that began in 1978 and ended with Ted Kaczynski’s arrest in 1996.

Wright posted Ted Kaczynski’s letter, dated April 4, on his Twitter account Sunday and wrote, “The Unabomber reached out. Thanks, Ted, you’re not nuts at all.” Wright was criticized for his remark on Twitter and later tweeted out that it was “unnecessarily snarky.”

It is not clear why Ted Kaczynski reached out to Wright, but he wrote in the letter that he would only speak to one person.

Fox8.com reported that David Kaczynski is the author of a book called “The Last Tie: The Story of the Unabomber and his Family.” The book details his brother’s struggle with mental illness.

Ted Kaczynski killed three people and injured nearly two dozen more by sending bombs through the mail over a two decade span. He was captured in April 1996 and sentenced to four life terms.
