Lisa Hagen

Lisa Hagen is the main villainess from "A View With a Room," episode 4.12 of Elementary.

She was played by Zabryna Guevara.

Lisa Hagen is a police detective who was also a villainous co-conspirator in a plot to rob a notorious biker gang. Hagen colluded with fellow detective Ryan Dunning in the plot, after Dunning's urges to raid the gang fell on deaf ears. Dunning and Hagen's plan was to get into a laptop computer that contained bank accounts belonging to the gang's leader, Nick Ferris, and once they took the computer, they decided to stage Dunning's murder to make it appear like he was killed by the gang.

Dunning fired a shot away from Hagen (who was playing Dunning in the scenario), but after Dunning's back was turned, the evil Hagen betrayed her partner and shot him to death; doing so in the exact same fashion as the fake murder. The villainess manipulated the video to keep their original ruse alive, but her plan was to have all of the gang's money to herself. After Sherlock pinpointed Dunning's appearance as a shooter, he deducted Hagen as the co-conspirator and killer when he noticed that she was the same height as the person behind the camera (5'7") and that she favored her left leg when she walked (as also shown in the video). Hagen was taken into Gregson's office by Sherlock, where her evil scheme was revealed, and she was later arrested.
