The trial for a Bucks County woman charged with aggravated assault for the beating of a gay couple drew closer toward an end Monday as the defense began presenting its case.

Witnesses testifying for the defense Monday denied that Kathryn Knott, 25, who is charged with aggravated assault in threw a punch during the melee, the Philadelphia Gay News reported.

She was one among a group of more than 12 who allegedly participated in a group attack on two gay men in Center City on Sept. 11, 2014 around 10:45 p.m. The attack left one victim with severe facial injuries that required him to have his jaw wired shut for months.

Victims Zachary Hesse and Andrew Haught, a gay couple, previously testified for the prosecution that Knott punched both of them after she and several friends shouted homophobic slurs at them.

But two witnesses for the defense, friends of Knott's, testified that she was not using offensive language or hitting anyone, the Gay News said.
