Justin Sharp is a college student and the adult boyfriend of teenager Carrie Lynn Eldridge. Carrie's mother Denise tried to have him arrested for statutory rape, then terrorize his life to try and scare him away from his daughter.
When Carrie bludgeoned Denise to death, as she would abuse Carrie regularly especially while she was drunk, Carrie Skype'd Justin, who rushed over, cleaned up the scene with her, and ran from the law with her to hide out in his family lodge. He was acquitted of murder and kidnapping, but he tried his best to cover for Carrie so she wouldn't be charged. She was tricked into confessing when she believed Justin sold her out and left, and when he told her the truth, she was furious at the Special Victims Unit for leading her on.
Justin was present at her sentencing of a plea deal for only serving a few years in prison, as Denise's abuse was revealed to be the motive. He hugged Carrie in a goodbye and waited for her release. (SVU: "Intoxicated")
