Did Leolah Brown uncover new evidence that would unmask the person responsible for Bobbi Kristina Brown's death?

In a cryptic post on her Facebook, Bobby Brown's sister wrote, "I Have Said It Once And I'm Going To Say It Again. IT AIN'T OVER! My Sister, Whitney Houston Brown And My Niece, Bobbi Kristina Brown, Have Not Left Us In Vain! And With The Help Of The Almighty God Allah, We Will Get Justice For Them Both!"

She has been screaming bloody murder after Bobbi Kristina Brown's death, not just pinning the blame of Nick Gordon but Whitney Houston's sister-in-law Pat Houston, as well.

Ruthie Trisch commented on Leolah Brown's post, "Some of the things I read about Whitney's last day and the way Bobbi K met her fate doesn't really add up. Nothing will bring them back but it sure would be nice to see the right person brought down and to justice! It all makes me sick really."

Juanita Smith chimed in, "Amen sis! I'm praying for you and your family cuz there is so much going on. But justice for Whitney and Krissi will come, and it will be really soon I feel. (sic)"

Pat Houston, meanwhile, spoke to Entertainment Tonight where she confirmed that prior to Bobbi Kristina Brown's death, the family was already planning an intervention and send her to a rehab facility in Georgia.

"When we really found out that Krissy was in trouble, we were really making plans to do something about it," she said. "But it came too late."

"Where the world saw that she was angry and mad at me, she was texting me all along," she said. "I really tried to show her [that] I'm going to do this to let you know that you don't have to be afraid of anything. I got you.'"

Nick Gordon is facing a multi-million civil action and wrongful death suit over Bobbi Kristina Brown's death.
