Karen Turner

Karen Turner is the true main villainess from Person of Interest episode 5.06, "A More Perfect Union."

She was played by Christina Bennett Lind.

Karen Turner is one of the daughters of Kent Turner, who owns a billion dollar horse breeding and racing business. Her father had been suspected of doping the horses for better results, but it was later revealed that Karen was the true culprit. Her evil deeds were caught on camera by Maggie Reynolds, a photographer for the family for 15 years, as well as a witness for the prosecution against Kent. Subsequently, the evil Karen attempted to have Maggie silenced; sending hitmen to kill her at the wedding of Karen's sister, Phoebe.

Karen's reveal came after Reese took out one of the gunmen, when she appeared with a pair of her henchmen. Maggie stated that she erased the photo, but it did not appease Karen, as Maggie could still testify. Karen ordered her henchmen to kill Maggie, only for both of them to end up shot and killed by Root, who rode in on a horse. Karen was subdued by Reese, and it was assumed that she was arrested for attempted murder.
