Tampa, Florida - George Russell Isbell, Jr. (69, San Diego, California) has pleaded guilty to mailing a threatening communication. Isbell faces a maximum penalty of five years in federal prison. No sentencing date has been set. U.S. Attorney Gregory W. Kehoe made the announcement.

According to court documents, on or about September 18, 2025, Isbell mailed an angry, offensive, and threatening letter from San Diego, California to his victim, a media personality located in Tampa, Florida. In the letter, he referenced one of the victim's friends, Mr. Charlie Kirk, a conservative political activist who, tragically, had recently been murdered during a public engagement on a college campus. The letter went on to state:

"Maybe someone will blow your head off!!! We can hope! Planning any public engagements? Love to see your head explode and your blood stain the concrete red. What a sight!".

This case was investigated by the Federal Bureau of Investigation. It is being prosecuted by Special Assistant United States Attorney Joseph Wheeler, III.
