A Northampton County man, who was sentenced to prison after authorities said he made threats on Facebook to blow up Dorney Park and shoot up a kindergarten classroom, wants the nation's highest court to hear his case.

Anthony Elonis, of Lower Saucon Township, has filed for a writ of certiorari with U.S. Supreme Court. The filing comes on the heels of a federal court of appeals denying his claim that his comments on Facebook were protected under the First Amendment. The filing claims the comments should not be considered "true threats" that are not protected under the First Amendment.

In 2012, Elonis was sentenced to 44 months in prison, plus three years of supervised release.

Elonis, police said, made threats on Facebook about Dorney Park, where he used to work.

Elonis also threatened his estranged wife, state police and the FBI and made remarks about shooting up a local kindergarten class, authorities said.

Prosecutors said Elonis posted on Facebook that he was going to commit "the most heinous school shooting ever imagined."
