She's the pretty daughter of a police chief, but 24-year-old Kathryn Knott is now on the other side of the law after a network of civilian sleuths used social media to track her down.
Surveillance video was their only clue. A group of preppy-looking 20-somethings were on a Philadelphia street. Just moments later, there was a brutal assault on two gay men.
The man in the mask goes by the name 'FanSince09' on Twitter. He used his network of 11,000 Twitter followers to track down the suspects in the video.
FanSince09 told INSIDE EDITION, "I basically just did some organizing and said, 'If anybody knows anything let's get this out there."

Within two hours they were identified as having partied at a popular Philadelphia restaurant.
Three people have been charged.
These two guys and Kathryn Knott, whose father, Karl, it turns out, is the police chief in a suburban Philadelphia town. They all deny any wrongdoing.
Her social media profile shows a photo of her drinking from a bottle of Fireball whisky.
One tweet reveals she once used her father's position as police chief to get special treatment.
She tweeted: "A guy ran me off the road. Called my dad ran his license, and got him ticket #lovemydad (@kathryn_knott)"
And: "Dad just let me kick down a door on a raid. Epic"
At an emotional rally protesting the attack, Caryn Kunkle, a friend of the two gay men who were beaten said they are slowly recovering.
Kunkle said, "One of the victims still has his jaw wired shut. He will have it wired shut for another seven weeks. They are both on a liquid diet. Neither one of them can eat solid food."
There won't be any more tweets from Kathryn for a while. Her Twitter page has been taken down.
