On Wednesday, the trial began for Kathryn Knott, the young woman accused of participating in a violent attack on a gay couple in Center City Philadelphia last year.

Knott, who hails from Bucks County, faces charges of aggravated assault, simple assault, conspiracy, and reckless endangerment.

According to Philadelphia police, she and a group of her friends beat the couple at 16th and Chancellor streets in September 2014.

Philip Williams and Kevin Harrigan both apologized, admitted their roles in the beating. Earlier this year, they both pleaded guilty to assault and conspiracy charges, agreeing to pay fines and participate in 200 hours of community service at an LGBTQ organization.

Neither received any jail time.

On the other hand, the 25-year-old rejected a plea deal, choosing instead to stand trial.

The trial began Wednesday.

A judge ruled that series of homophobic tweets written by Knott can be used as evidence against her.
