ITHACA, N.Y. — An Ithaca man faces multiple weapons charges after police responded to a report that he was threatening a woman with a gun, according to an Ithaca Police Department media release issued Monday.

Officers responded to a call at about 1 p.m. on Wednesday, July 31 reporting that a man was threatening his girlfriend with a gun. When officers responded, the victim reported that Jon Ross, 36 of Ithaca, had held her against her will, threatened her with multiple firearms, and subjected her to unwanted physical contact, police say.

A police investigation found multiple weapons and ammunition inside Ross’s apartment, including an assault rifle, two sawed-off shotguns and brass knuckles. Police allege Ross possessed all of the weapons illegally.

All weapons and ammunition found in Ross’s residence were confiscated during the investigation.

Ross is charged with three counts of third-degree criminal possession of a weapon, a Class D felony, as well as single counts of second-degree unlawful imprisonment, second-degree menacing and fourth-degree criminal mischief, all Class A misdemeanors. In addition, he faces one count of second-degree harassment, a violation.

Ross was arraigned by Judge Richard Wallace in Ithaca City Court and remanded to Tompkins County Jail on $5,000 cash bail or $10,000 bond. He was released from Tompkins County Jail on Monday.
