Christopher Brown, 21, of Aquebogue, Suffolk County, New York, United States was with Matthew Mahrer, 22, of Manhattan, New York City, New York on November 19, 2022. They were entering Penn Station in Manhattan when they were arrested by Metropolitan Transportation Authority officers.
Brown was charged with making a terroristic threat, aggravated harassment and criminal possession of a weapon while Mahrer was charged with criminal possession of a weapon. The charges were in connection with online threats to attack a synagogue in New York City.
On November 12, 2022, the threats started appearing on a Twitter account. One post read, “Gonna ask a priest if I should become a husband or shoot up a synagogue and die”.
On November 18, 2022, the threats were traced to a computer at a veterinary clinic where one of the suspects worked. After being alerted to the online messages, agents from the Federal Bureau of Investigation‘s Joint Terrorism Task Force and detectives from the New York City Police Department’s intelligence bureau started efforts to identify and locate the suspects.
After the arrests of Brown and Mahrer, they were turned over to the NYPD and the FBI. Before going to Penn Station that day, the suspects dropped off a backpack in a Manhattan address associated with a friend.
The backpack was recovered with a laser sight, a Glock semi-automatic firearm and a ghost gun with an extended 30 round magazine. One of the suspects also had a black ski mask, a large knife, a Nazi armband and a semi-automatic weapon.
