According to the New York Daily News, Buckel was found with a suicide note. The note read: “I am David Buckel and I just killed myself by fire as a protest suicide.

“I apologize to you for the mess.”

A second suicide note was marked “for the police” and read: “My early death by fossil fuel reflects what we are doing to ourselves.
