James Reardon, 20, of New Middletown, was indicted on Friday in U.S. District Court with one count of transmitting an interstate communication threat and one count of possession of a firearm in furtherance of a crime of violence, the U.S. Attorney’s Office for the Northern District of Ohio said in a statement.

“This defendant’s video demonstrated that he had access to weapons and he posed a threat to a Jewish community center.  Law enforcement cannot wait to see if a shooting is going to occur, law enforcement must act quickly within the confines of the law to disrupt any potential violent act,” FBI Special Agent in Charge Eric B. Smith said.

Reardon previously pleaded not guilty to charges of telecommunications harassment and aggravated menacing in municipal court in Struthers, near Youngstown. The judge a mental health evaluation and also ordered Reardon to stay away from synagogues and Jewish organizations.

A video posted on Instagram in mid-August showed Reardon shooting an assault rifle accompanied by the sounds of sirens and screams. Under the video Reardon added the caption “Police identify shooter of Youngstown Jewish Family Center as local white nationalist Seamus O’Rearedon,” one of his pseudonyms. The Youngstown JCC was tagged in the post.

A search of his home in the Youngstown suburb of New Middletown found assault weapons, extra ammunition and a gas mask, as well as anti-Semitic and white nationalist propaganda. He attended the “Unite the Right” rally in Charlottesville, Virginia, in 2017.
