Leolah Brown, the aunt of Bobbi Kristina Brown and sister of R&B singer Bobby Brown, made a shocking claim Thursday when she alleged in a Facebook post that Bobbi Kristina and her late mother, pop legend Whitney Houston, were murdered. Leolah claims to be a beacon of truth.

It’s no secret that the Brown and Houston families don’t get along. Leolah started her post by slamming Pat Houston, Whitney’s sister. But then things took a sinister turn when Leolah said Whitney and Bobbi Kristina were victims of foul play.

Leolah wrote that she stayed quiet until after both Whitney and Bobbi Kristina had died.  "I never have said anything until Whitney was murdered and now my niece Bobbi Kristina!” she wrote in the most alarming part of the Facebook post.

Pat apparently started a foundation, the Marion P Foundation, on behalf of Bobbi Kristina, Leolah wrote a day earlier. Appalled, she lashed out at Pat. “This is part of the proof that her intentions are very ill,” Leolah wrote.

Infuriated that Pat did not retaliate, Leolah wrote another post. “Yes, she's quiet without saying a word. But, believe me it's not because she does not know I am revealing her. She would really want you and the media to think that my words are irrelevant or maybe I'm just looking for attention. But that is so very very far from the truth -- if you only knew,” Bobby Brown’s sister said.

Leolah has been vocal on social media since Bobbi Kristina was found unconscious in a bathtub in her Roswell, Georgia, home Jan. 31. Leolah shared her disdain for the Houstons, especially Pat, throughout this time.

The Brown and Houston families have reportedly not been able to compromise on funeral arrangements for Bobbi Kristina because of their feud. “Both sides [of the family] are still not happy and on the same page," a source told People magazine. "There is a lot going on behind the scenes. There is a lot to do in a very short time." Another source reportedly said: "Things are constantly changing."

Bobbi Kristina died Sunday at Peachtree Christian Hospice in Duluth, Georgia, after months of hospitalization. She was 22.
