Plattsburgh City Police say Justin Herzog, who was due to be arraigned Monday morning on second-degree murder charges, committed suicide later that day. 

Herzog, 44, was pronounced dead shortly after 5 p.m. Monday in his Plattsburgh law office, the Clinton County Sheriff’s Department said.

Herzog failed to appear for Monday’s arraignment on seven felony charges related to a Febraury domestic assault on Jill Carey-Herzog. A warrant was issued for his arrest.

Hours later, his body was found after police received a call to his office on U.S. Avenue about an unconscious male who was not breathing.

Autopsy results have not yet been released. But the death has been ruled a suicide.

Police say Herzog threatened Carey-Herzog and male juvenile with a knife in a Chazy residence on February 18. Carey-Herzog was wounded during a struggle over the weapon. Police say Herzog also attempted to strangle Carey-Herzog.

Herzog represented Clinton County prison worker Denise Prell, who received a two-year sentence in 2018, after admitting to having an affair with an inmate. She pleaded guilty to second-degree promoting prison contraband, third-degree sexual abuse and official misconduct.
