SPOKANE, Wash. - A 37-year-old 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 lives in a rundown apartment building near downtown Spokane.
Matthew Ryan Buquet is originally from Bogota, Colombia.
He remains in jail after appearing in federal court Wednesday and pleading not guilty to a charge of mailing a threatening communication.
He is a registered sex offender from a 1998 conviction for taking indecent liberties with a 10-year-old girl. He most recently worked as a janitor at ABM Janitorial Services in Spokane.
