Bryanna Barozzini, who was 18 at the time of the incident and 20 by the time it was resolved, pleaded guilty to involuntary manslaughter and received a three-year prison sentence in the death of 17-year-old Halia Culbertson after a confrontation in northeast Columbus, Ohio.

Barozzini was initially charged with murder and related counts. On the eve of trial in June 2024, as jury selection approached, she accepted a plea agreement under which prosecutors dropped the murder counts. Franklin County Judge Mark Serrott imposed the maximum three years available under the plea on July 11, 2024, along with related terms such as a potential fine. Early-release consideration was noted as possible later. Culbertson's family members expressed strong dissatisfaction with the reduced charge and sentence during impact statements.

Barozzini, of Westerville, and Culbertson, of Sunbury, were former best friends from the Columbus area who had fallen out and were engaged in an ongoing feud involving mutual animosity and exchanged threats. Prosecutors described "bad blood" and "unjustifiable rage," while the defense maintained Barozzini acted out of fear. Barozzini later admitted carrying a knife from work for protection. Earlier text messages referenced slicing Culbertson's throat or cutting her if she came near again or went to her family's home.

At about 11:48 p.m. on March 26, 2023, the two encountered each other inside 161 Carryout, a smoke shop and convenience store near Emporium Square and Cleveland Avenue in the Northland area. Culbertson challenged Barozzini to a fight, and staff asked Culbertson to leave. Culbertson waited outside, then threatened, pushed and slapped Barozzini in the face when she emerged.

Surveillance and bystander video showed Barozzini stepping or backing away, reported in defense filings as at least 30 steps, before drawing a knife and swinging once. The knife struck Culbertson in the neck, clavicle or chest area. Culbertson continued engaging briefly and noticed the blood only later. She was taken to OhioHealth Riverside Methodist Hospital and died early on March 27 from the single stab wound. Barozzini left the scene.

Witnesses identified Barozzini, and police found her at her Westerville home. She admitted swinging the knife during the fight but claimed self-defense and said she had limited memory of the strike. Police recovered the knife from a crawl space and found clothing in a washing machine. Bodycam footage recorded aspects of her interaction with officers.

Investigators also obtained the prior text messages and video of Culbertson initiating the confrontation and slapping Barozzini before the stabbing. A judge indicated the messages would have been admissible and could undercut a pure self-defense claim. Prosecutors acknowledged Culbertson was the initial antagonizer and aggressor in the parking-lot encounter, but said using a knife was a disproportionate response to a slap.

The video is about 29 minutes of police interview-room footage. It presents the interview itself, with no narration or presenter.
