Nadia Decotis was a drug-addicted prostitute-turned-employee for the Chicago Police Department.
Nadia was arrested for prostitution by Detective Erin Lindsay, who helped her become clean. Afterwards, Nadia began to work with the Intelligence Section of the Chicago Police Department and study Criminology at college with hopes of becoming a police officer.
Yates held her captive and took her on a road trip from Chicago to New York. Upon arriving at New York, he raped, tortured, and ultimately murdered Nadia, but not before she left behind her scarf as evidence. Yates was later arrested and convicted of rape, sodomy, and first-degree murder concerning her case. (SVU: "Daydream Believer")
