It’s no secret that mother and daughter Whitney Houston and Bobbi Kristina Brown’s deaths are eerily similar as they both passed away after being found unconscious in bathtubs.

Houston’s body was discovered in a Beverly Hills hotel on Feb. 11, 2012 while Bobbi Kristina was found on Jan. 31, 2015. She died on July 26.

While both autopsy results have said that drugs were involved in both cases, Leolah Brown, who is the sister of Bobbi Kristina’s father and Houston’s ex-husband, Bobby Brown, has said that drugs were planned to be used as the cover-up for their cases all along.

She commented on Facebook Monday, “It was all planned to say it was drugs in the first place…”

She added that her upcoming book will explain it all and fans will be able to “see for yourselves the evidence that I DO HAVE…”

Leolah went on to point out that there should be surveillance of what really happened to Houston.

“Of course they had cameras! That’s a 5 star hotel! Even the smallest business in this world have cameras! Especially hotels! Whitney’s death & murder should have BEEN solved! It was way too easy to solve!!! INCREDIBLY EASY!!!”

On top of that, Leolah has said in the past she is convinced that Ray J was involved. While the singer turned reality star has shut down those rumors and threatened to take legal action, Leolah is still unbothered.

“Oh well, he might wanna go ahead and get his lawyers ready because his name is all up in my book and I have evidence & proof that he was there so he may just as well be ready!”

No word on the title of the book or when it will be released.
