From what ive seen on tv and reports from Bobby brown/fammily they where worried about her drinking and taking valium while in the tub cause she apperantly been known to pass out while in there. She was found upside down in the tub. Valium and other pill bottles where found in her room. allong with alcohol. So im deducing is she sedated herself with the valium increased its effects with the alcohol and drowned in the tub. Her fammily also stated I saw this on E (I know... Cheeks makes me watch it) that they didnt like her taking baths for fear she would drown.
