Overview

• Isbell, 69, was arrested on Oct. 7 in San Diego and is charged in federal court with mailing threatening communications, a crime punishable by up to five years if convicted.
• The complaint quotes the letter as calling for Johnson’s “extermination,” saying he should be “strangled by an American flag,” and adding, “Maybe someone will blow your head off.”
• FBI, U.S. Postal Inspection Service, FDLE, and Tampa police traced the mailing to San Diego and matched fingerprints found on the envelope.
• The letter arrived days after Charlie Kirk’s assassination and referred to Johnson as “Charlie Kirk Jr,” according to prosecutors.
• Attorney General Pam Bondi characterized the suspect as a left‑wing radical and warned against copycat threats, while the FBI pledged continued investigations and prosecutors sought Isbell’s detention at a Friday hearing.
