Arian O’Connor Gets 10 Years for Illegal Firearm Possession

A Youngstown man with a violent criminal past is headed back behind bars for a decade after being caught with a high-powered rifle. Arian O’Connor, 39, also known as Noble Bullhorn Sirius O’Connor Bay, was sentenced to 10 years in federal prison for being a felon in possession of a firearm, U.S. Attorney Carole S. Rendon and ATF Special Agent in Charge Trevor Velinor announced today.

The charge stems from an incident on or about August 12, 2015, when O’Connor was found in possession of a Maddi Company, Model Arm, 7.62 rifle. Despite multiple prior convictions—including felonious assault and two previous counts of being a felon in possession of a firearm—O’Connor chose to illegally arm himself, placing the public at grave risk.

Court documents lay bare a pattern of defiance. O’Connor isn’t just a repeat offender—he’s a walking violation of federal gun laws. Each prior conviction should have served as a warning. Instead, he continued to traffic in weapons, treating court orders and public safety with utter contempt.

The investigation that led to his latest conviction was a joint effort between the Bureau of Alcohol, Tobacco, Firearms and Explosives, the Youngstown Police Department, and the U.S. Probation Office. Their collaboration dismantled O’Connor’s ability to further endanger the community, closing a chapter on a long-standing threat.

Assistant U.S. Attorney David M. Toepfer prosecuted the case, pushing for maximum accountability under the law. “This sentence sends a clear message,” Toepfer stated. “If you’re a convicted felon and you pick up a gun, you will go to prison. Again. For a long time.”

O’Connor’s 10-year sentence underscores federal zero-tolerance for illegal firearms possession—especially among violent offenders. With a criminal alias and a trail of gun charges, his name now adds to the growing list of those who tested the system and lost.
