Carter also lost his father, Robert Carter in 2017 and his other sister, Leslie, in 2012.
"We are taking it one day at a time and coping with it the best way we can," he said of his family in 2017 following his father's death. "Nobody can ever prepare for anything like that, regardless of my issues with my family. He’s still my father. So obviously, I’ve been conflicted, sad, mourning, angry, and all the different things that you go through in that process of grief. But again, we’re dealing with it the best way we can."
