A bride allegedly murdered her niece outside a Pennsylvania bar Thursday night following an argument over who was going to drive home from the establishment.

Christina George, 30, allegedly shot and killed her niece, 21-year-old Katelyn Francis, of Fairview, W.Va., as the aunt and niece celebrated George’s wedding with her groom, Jeremy Harvan, around 10 p.m. Thursday, the Pittsburgh Post-Gazette reported. Francis is being held in the Beaver County Jail. She is scheduled to be arraigned on homicide and other charges Friday, according to the paper.

Francis was shot in the New Brighton, Pa., bar’s parking lot after she and her aunt got in a dispute over who would drive home, CBS Pittsburgh affiliate KDKA reported. George’s husband was allegedly intoxicated, which sparked the fight over who would drive, Pittsburgh television station WTAE reported. George then allegedly pulled out a gun and shot her niece.

Witness James Boitinovich described the scene for KDKA.

“Everybody in the bar noticed that there was something going on with the people, but nobody knew exactly what was happening,” he said. “The next thing you know we heard someone got shot … looked out, noticed it was right by my car.”

Police told the Post-Gazette they believe the gun used in the killing, a .9mm Glock pistol, was owned by Harvan.

In addition to homicide, George is also facing charges of aggravated assault and recklessly endangering another person.
