A jury is set to start deliberations Wednesday in the felony assault trial of 25-year-old Kathryn Knott of Southampton, Bucks County.
Knott is charged with shouting slurs and punching one of the victims as her friends left a birthday celebration in the city.
Two male co-defendants have pleaded guilty and received probation and a ban on coming to Center City.
Knott testified Tuesday that she tried to intervene and never punched or insulted the victims.
She admits to using anti-gay language in tweets about a bad hair day or a lame song.
The September 2014 attack left one victim hospitalized and prompted the city to add sexual orientation to its hate crime law.
