A state prison inmate who lived in Canaan recently and threatened Gov. Paul LePage last year is scheduled to be arraigned Monday in federal court in Bangor on charges that he threatened President Obama.

Leroy Eugene Dunn, 30, is accused of writing a letter in April saying he would kill the president, according to an indictment filed Jan. 12 in U.S. District Court.

The indictment alleges that Dunn said in a handwritten letter, “I hate you and will do anything I can to get rid of you … You will die at my hands … I will kill you Barack Obama.”

Assistant U.S. Attorney James Moore said the letter containing the threat was addressed to the president and placed in the outgoing mail by Dunn while he was an inmate in the Piscataquis County Jail in Dover-Foxcroft.

Maj. David Allen, administrator at the jail, said Dunn was brought there Wednesday by U.S. marshals.

The case was investigated by the U.S. Secret Service.

Dunn has been in the Maine Correctional Center in Windham, serving a three-year sentence for drug trafficking.

Dunn pleaded guilty to terrorizing in February 2011 for threatening LePage while Dunn was in the Piscataquis County Jail. In that case, Dunn detailed a plan to kill the governor and slipped the message under his cell door.

Dunn was sentenced to 60 days in jail for terrorizing, the Piscataquis County District Attorney’s Office said Thursday.

Dunn’s mother, Philomena Gordon of Bingham, said Thursday her son is mentally disabled and suffers from the effects of Marfans syndrome, a disorder of the body’s connective tissues that can cause disproportionately long arms and legs, among other symptoms.
