Leolah Brown: My Niece Bobbi Kristina and Whitney Houston Were Murdered

By INSIDE EDITION

Leolah Brown has told INSIDE EDITION that she believes Bobbi Kristina Brown was murdered -- and so was her mother, Whitney Houston.

In an exclusive interview that will air in full on Wednesday, Leolah -- the older sister of Bobbi Kristina's father Bobby Brown -- spoke about losing her 22-year-old niece this summer.

"This was no accident," she said. "I will never believe this was an accident ... I believe that somebody killed my niece, just like they killed her mother."

In January, Bobbi Kristina was found face-down in a bathtub in the Georgia home she shared with her boyfriend Nick Gordon. Nearly six months later, she passed away in hospice care.

Leolah told INSIDE EDITION that she believes Gordon is to blame.

"Nick murdered Bobbi Kristina," she said. "When Nick gets arrested, I think everything will fall like dominoes."

Nick Gordon has never been arrested or charged in connection with Bobbi Kristina's death. He has denied any wrongdoing.

Leolah continued: "I believe that several people wanted Bobbi Kristina dead... I think the purpose of her death was to gain full access to Whitney Houston's estate."

Houston died of an accidental drowning in a Beverly Hills hotel room in February 2012, when she was 48.

"I believe that Whitney was murdered," Leolah added. "At some point we have to wake up and realize this is too close, too similar - mother, daughter, both in bathtubs... Something is very, very wrong with that picture."

Leolah also spoke to INSIDE EDITION about her dramatic outburst during Bobbi Kristina's funeral and the young woman's last few days in the hospice. Watch INSIDE EDITION on Wednesday for more of the exclusive interview.
