Dr. Constantine (first name unknown) is a forensic pathologist who was responsible for handling the remains of rape and murder victim Susie Marshall. Hoping to offer her more than just a face, when he made his composite from her skull, he nicknamed her "Cherish Doe" so she could be released to the media and have more of a personality to be identified from.
He estimated her age to be six, and he did the hard work of cutting the joints in her wrists so her hands could be soaked in embalming solutions to restore her fingerprints. When her face was released, she was identified, but also briefly mistakenly identified as Nina Tremain by her mother Violet Tremain. It turns out Nina was kidnapped by the same killer, Terry Jessup. Tracking him led to Nina's rescue in time and justice for Susie. (SVU: "Dolls")
