Members of Bobby Brown’s family say there are still many unanswered questions and hidden details about Whitney Houston’s death. Brown’s sister, Leolah Brown, tells HLN’s “Dr. Drew” she believes singer Ray J, whom she says Whitney called a “runner boy,” was directly involved in what happened to the legendary singer on the evening she died.

Leolah also casts blame on Whitney’s brother Gary and his wife Pat, saying they should have been watching out for the singer but instead turned a blind eye to her substance abuse. Brown is also expressing her concern for Whitney’s daughter, Bobbi Kristina. She explains that the Brown family doesn’t think any of the people surrounding Bobbi right now are looking out for her, and don’t have the girl’s best interest at heart. Bobby Brown’s nephew Jairam Reid says he’s particularly suspicious of Bobbi’s rumored boyfriend, Nick Gordon, and believes he’s “up to something.”

Leolah says she also found it strange that Whitney was discovered dead in the bathtub of her hotel room. She explains that Whitney never took baths when she stayed in hotels, because she didn’t trust that the were truly clean.
