Nashville Man Charged with Being a Felon in Possession of a Firearm After Allegedly Pointing a Stolen Rifle at Police

NASHVILLE – Isaiah Taivon Newsom a/k/a Isaiah Taivon Porterfield, 25, of Nashville, has been charged by criminal complaint with being a felon in possession of a firearm, announced Acting United States Attorney Robert E. McGuire for the Middle District of Tennessee.

“Dangerous felons who possess firearms and put police officers at risk will face swift justice,” said Acting United States Attorney Robert E. McGuire. “We will not tolerate potential violence against first responders and will seek full accountability for those putting our first responders in danger.”

According to court documents, on March 25, 2025, detectives with the Metropolitan Nashville Police Department were conducting covert surveillance near an address on Nashboro Boulevard. Detectives were parked in their unmarked police vehicles in several different areas of the apartment complex. One detective observed three people walk out of the breezeway near unit B, with one, later identified as Newsom, carrying what appeared to be a rifle.

As they walked through the apartment complex, Newsom walked about fifteen feet away from another detective’s unmarked vehicle, stood near a tree, raised the rifle to his shoulder and pointed it at the detective, who was still in his vehicle. As the detective relayed Newsom’s actions to the other detectives in the area and they discussed a plan of action over the radio, Newsom walked past the front of the detective’s vehicle towards the passenger side and again pointed the rifle at the detective.

As other detectives arrived in the area, Newsom moved towards the front of the detective’s vehicle and pointed the rifle directly at the detective. Although he was in an unmarked car, the detective was wearing a tactical vest with patches indicating he was a law enforcement officer, and he was equipped with a body worn camera. The detective activated his blue lights and a short burst of the siren, as he exited the vehicle and announced himself as a police officer. Newsom and the other two people then ran from the area. Detectives pursued Newsom on foot as he ran across a field and entered the wood line. Detectives set up a perimeter and, with the assistance of a K9 unit and the Metro Nashville Police Department aviation unit, took Newsom into custody.

Detectives searched Newsom’s flight path and located a Windham Weaponry, WW-15, .223/5.56 caliber rifle which was later found to have been reported stolen from a Williamson County Sheriff’s Office marked patrol vehicle. After being advised of his Miranda rights, Newsom admitted to detectives that he had possessed the rifle.

Newsom had previously been convicted of two counts of aggravated robbery and two counts of felony theft in Shelby County, Tennessee. Newsom served more than seven years in the Tennessee Department of Correction for his felony convictions.

If convicted, Newsom faces a maximum of 15 years in federal prison and a maximum fine of $250,000.

This case is being investigated by the Bureau of Alcohol, Tobacco, Firearms and Explosives, and the Metropolitan Nashville Police Department. Assistant U.S. Attorney Rachel M. Stephens is prosecuting the case.

This case is part of Project Safe Neighborhoods (PSN), a program bringing together all levels of law enforcement and the communities they serve to reduce violent crime and gun violence, and to make our neighborhoods safer for everyone. On May 26, 2021, the department launched a violent crime reduction strategy strengthening PSN based on these core principles: fostering trust and legitimacy in our communities, supporting community-based organizations that help prevent violence from occurring in the first place, setting focused and strategic enforcement priorities, and measuring the results.

A complaint is merely an allegation. The defendant is presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
