(CNN)As Bobbi Kristina Brown remains in a medically induced coma fighting for her life, little information about the incident at her Atlanta-area home or her condition has slipped from police or family. If the investigation into what happened to the 21-year-old only child of Whitney Houston has revealed much, no one is talking publicly about it. We do know this: Brown was discovered facedown in a bathtub at her Roswell, Georgia, home over the weekend, and she was reportedly found by the man she has called her husband, and a friend. Here's what we know about the players involved in the story.

Whitney Houston left estate to daughter; it was to be doled out over years
@placeholder had lived with Houston and her daughter since he was 12 years old.
@placeholder's father is as much known for his shenanigans as he is for his music, if not more.
He married Houston in 1992, and the story line surrounding @placeholder would quickly become one of cocaine, booze, rehab, arrests and alleged violence against Houston, who filed for divorce in 2006.
According to her will, which she signed about a month before @placeholder's 1993 birth, her daughter was the sole heir to her estate.
