Gay's mother was murdered in a domestic violence incident when he was eight years old. Apparently, Gay and his siblings knew nothing about the domestic violence occurring in his home, but at the urging of other family members, and out of fear for her children, she left her boyfriend—the father of Gay's brother. While she was at a friend's house shortly after leaving, her boyfriend arrived at the friend's house and shot her three times. The boyfriend then went back to his car and killed himself. In an effort to keep them together his grandmother took the brothers in and raised them. He shared his story in a video for the Women's Center and Shelter of Greater Pittsburgh in an attempt to spread the word on domestic violence.As of August 2015.

Gay played college football at the University of Louisville where he played in 46 games recording 134 tackles.
