SPOKANE, Wash. — A 37-year-old janitor who has been charged with threatening to kill a federal judge in a case that involves letters containing the poison ricin is a registered sex offender who lived near downtown Spokane.
Matthew Ryan Buquet remained jailed Thursday after appearing in federal court a day earlier and pleading not guilty to a charge of mailing a threatening communication.
Buquet is a registered sex offender because of a 1998 conviction for taking indecent liberties with a 10-year-old girl, according to the Spokane County Sheriff’s Office.
He served 18 months in jail.
Wednesday’s grand jury indictment accuses Buquet of mailing a death threat to US District Judge Fred Van Sickle in Spokane on May 14.
