Bobbi Kristina Brown's aunt charges her still unburied niece and her mom Whitney Houston were both murdered.

Still days before 22-year-old Bobbi Kristina is expected to be laid to rest and later buried alongside her mom in New Jersey, the angry sister of father Bobby Brown took to Facebook on Thursday to voice all her latest rantings.

"Whitney was murdered and now my niece Bobbi Kristina," Leolah Brown wrote. While she didn't name those she may suspect, RadarOnline reports authorities have launched a criminal probe that targets Bobbi Kristina's 25-year-old live-in boyfriend Nick Gordon as a suspect. In addition, co-conservators of her estimated $20 million estate recently slapped Gordon with a $40 million lawsuit that alleges he physically abused his girlfriend throughout much of their relationship.

In her post, Leolah took direct aim at Bobbi Kristina's aunt Pat Houston.

"You notice, no matter what I say, Pat never says anything following, to at least defend herself?" she posted. "Just think about it. Use your God-given brains. if, what I was saying was untrue or just talking for no reason at all (which anyone that knows me knows that my character is just simply not that), why would she not defend herself if I am wrong? But, I am saying this for people who are curious as to why there is no talk back from Ms. Pat regarding my statements made about her. I will tell you. Because SHE CANNOT talk back to truth. She has no leg to stand on."

The only daughter born to Bobby Brown and Whitney Houston died late last week under hospice care at an Atlanta facility. She never regained consciousness after being rushed to a hospital emergency room nearly six-months ago after being found face down in the bathtub of her Roswell home.

Whitney Houston died almost three years earlier when she too was found face down in the bathtub of a Beverly Hills hotel where she was residing. Back then, the Grammy Award-winning singer was in town to participate in that year's award show and authorities later revealed she had drugs in her system at the time of her death.
