CORTLAND, Ohio (AP) — A teenager was arrested after a leader of the Church of Satan turned over to the FBI an e-mail the high school student had written to the sect in which he threatened to kill his grandparents, authorities said.

Andrew Culver, 18, told police the e-mail detailing his intention to kill his grandparents and steal their money and car was a joke, said Bazetta township Police Chief Charles Sayers.

According to police, Culver wrote he had access to an arsenal of weapons and wanted to "kill in the name of our unholy lord Satan."

Culver sent the message Wednesday to Peter Gilmore, the high priest of the New York City-based Church of Satan, Sayers said. Gilmore alerted the FBI, which notified local police. Charges will be discussed at a scheduled hearing on Monday, Sayers said.

Gilmore said members of his group are atheists who believe Satan is a symbol of freedom, not evil. "To the Satanist, he is his own God," reads a statement on the group's Web site from Gilmore.
