Kathryn Knott, the 25-year-old suburban Philadelphia woman found guilty of participating in a group attack on a gay couple in downtown Philadelphia, began serving her 5 to 10 month jail sentence on Monday.

The victims of the 2014 attack told police that they were rushed by a mob of 10 to 12 men and women after one asked them if they were together. As a result of the beating, one of the victims was hospitalized for more than three days and had to have his jaw wired shut.

Common Pleas Judge Roxanne Covington also ordered Knott, a former hospital worker, to get anger management treatment for her numerous online posts attacking gays, Middle Easterners and hospital patients.

“While these were homophobic slurs that started this incident, it could have been any type of hate speech,” Covington is quoted as saying by the AP. “It could have been anyone.”

The victim spoke briefly at Knott's sentencing hearing: “This whole group of people left us. … Every single one of that group, including Kathryn Knott, left me in that alleyway to die.”

Of the three accused, Knott was the only one to refuse a plea deal and go to trial, where a jury convicted her of four misdemeanors, including simple assault.
