BANGOR – The man who torched the Skowhegan State Fairgrounds has been indicted by a federal grand jury for making threats against former President Bill Clinton while in custody.

Charles D. Miles, 25, was indicted Jan. 26 by a federal grand jury on two counts of mailing threats against the president. If convicted, he faces up to five years imprisonment and a fine of up to $250,000 on each count.

The affidavit, signed by a Secret Service agent, included information about a threat against President George W. Bush. Miles was not indicted for making threats against Bush.

Miles was committed five years ago to the former Augusta Mental Health Institute after he was found not criminally responsible for setting the March 1999 fire that leveled the historic grandstand and exhibition hall. The fire caused $3 million in damage.

His defense attorney, Janet Mills of Skowhegan, said then that Miles had a neurological disorder caused by being dropped on his head on a concrete floor when he was a month old. Miles has lived most of his life in state custody in foster care and mental institutions, she said in 1999.

The first of two letters in which Miles allegedly threatened Clinton was postmarked Jan. 28, 2000, and sent to the federal Drug Enforcement Agency’s office in Portland. It included Miles’ name and listed his address as AMHI in Augusta, according to court documents made public on Friday. A second letter containing Miles’ name and AMHI’s return address was received at the White House on Feb. 9, 2000.

While the first letter threatened to “kill the President and his dope family,” the second also directly threatened first lady Hillary Clinton and the couple’s daughter, Chelsea.

Both letters are full of misspellings, grammatical errors, run-on sentences and profanities.

“[Y]ou will die for the problem you caused you cant stop me I see your guts all over the floor you dumb gay, …” the second letter states. “Six million ways to die Billy Boy choose one.”

Miles is being held at the Maine State Prison in Warren. He was sentenced to serve a year there after he escaped from AMHI on Dec. 25, 2003. He was to have been released on Jan. 20 and returned to the Riverview Psychiatric Center, formerly AMHI, but remains in prison detained on the federal indictment.

He also is facing an aggravated assault charge in Knox County for a fight in prison, according to the U.S. attorney’s office.

U.S. District Court documents filed in Bangor also described a letter that was received at the White House in September 2004 and allegedly was sent by Miles while he was in prison. That letter, which was similar to the others, included a threat to kill Gov. John Baldacci and contained a white substance.

“Just writing to let you know im going to murder you!” Miles allegedly wrote in his letter to Bush. “im going to murder your whole family … Don’t feel bad im killing the Governor of Maine to John Elias Baldacci. And his family. Your all gonna DiE. By the way heres some anthrax for you. Cant wait to see you dead.”

A Secret Service agent interviewed Miles at the prison on Jan. 11, according to court documents. Miles allegedly admitted writing the letters and said that if he were released from custody, he intended to act on the threats. He allegedly said that the white substance in the letter was salt that he had collected from the packets provided with meals by the prison.

Miles, however, was not indicted for sending that letter to Bush. If convicted of threatening Clinton, officials could wait until he has served his sentence on those charges, before asking a grand jury to indict him for threatening Bush.

Eventually, Miles is expected to be returned to Riverview Psychiatric Center, where he is to remain committed until he can prove he is no longer a threat to himself or others.
