Page Ferguson was an A.D.A. who was investigating a missing stash of drug money in an investigation, realizing one of her colleagues stole them. Her boyfriend, Detective Investigator Sean Riggs, took a polygraph to not endanger their relationship from Ferguson having to question him. She suffered from aggressive masochism from the chaos and danger of her job, mutilating and battering herself and often putting Riggs in the light of "domestic abuser".
Ferguson was horrified to find her best friend, Sunny Qadri, who she was working with since their work together in Brooklyn offices, stole the money and gave her a warning to turn herself in and give the money back. Qadri reacted with arranging a snitch of hers and his girlfriend to torture Ferguson under the ruse she was the one with the money, then arrived at where her car was to witness her being thrown off a rooftop and give herself an alibi. Qadri also resented Ferguson's career was shaped by Qadri's contacts and Qadri never made it to Captain.
All the scandals of the office came out, and Ferguson's killers were arranged to be murdered at Qadri's direction. She was eventually found out, the drug money was returned, and she was arrested and charged with murder contracting. (SVU: "Dirty")
