An Arkansas man has plead guilty to sending threatening letters to judges and other federal personnel in Memphis.

Back in March 2018, court documents show the United States Clerk's Office for the Western District of Tennessee received a bomb and violence threat in the mail in the 160 block of North Main Street.

Patrick Hayden, 32, from Charleston, Arkansas plead guilty to sending the letters.

Officials said an envelope postmarked March 2, 2018 was forwarded from inmate Arron Lewis from Marianna, Arkansas.

Investigators said the envelope contained several letters from four Arkansas state inmates and a note stating ‘"federal employees there is a bomb in the building! 901 confederates #savethestatues."
