A 51-year-old man from Illinois has been sentenced to five years of probation after pleading guilty to making anti-Semitic threats against an Arizona attorney.

Kevin Thomas Kerr also received six-months of house arrest and spent slightly longer in jail.

An FBI agent wrote in a probable cause statement that for months in 2020 Kerr sent threats to a Phoenix attorney working at a national firm. A client of the lawyer was Kerr’s former employer, which he’d threatened to sue after getting fired.

The agent wrote that Kerr insinuated that the lawyer was part of a Jewish mob stalking Kerr and claimed signals were being sent into his head by directed energy weapons.

Records show Kerr admitted threatening to rip the lawyer’s skull in half and making anti-Semitic slurs.

A plea deal with the government requires Kerr to get mental health testing and treatment while on house arrest and probation.
