Bobby Brown's sister Leolah Brown does not believe Whitney Houston's death was accidental...
From Access Hollywood
''I believe Whitney's death was not accidental. No.''
She refuses to speculate about who she thinks is responsible, but added: ''My attorney has advised me not to get into that at all, but, it's very important to know that she did not just pass away like that. No. And if it's the last thing that I do, I'm going to find out what truly happened to my sister.''
