Bobbi Kristina Brown’s aunt, Leolah Brown, penned two short declarations promising to reveal the truth about her niece’s death. Leolah, the sister of singer Bobby Brown, has spoken out several times in the past, claiming Bobbi Kristina’s death was not an accident.

“Everyone ‘thinks’ they know the truth- BUT it will only come from ME. One day soon the world will know and we will all be set FREE,” Leolah wrote in one Facebook post Friday. “Until that day-just be patient- as I do what I have to DO. I promised not to let you none down- and I won’t-from me to YOU.”

In a second update, Leolah wrote that Bobbi Kristina and her mother, Whitney Houston, didn’t deserve to die. Bobbi Kristina died July 26, 2015, after being found unresponsive in a bathtub inside her Georgia home in late January 2015. Houston died on the eve of the Grammy Awards in Los Angeles on Feb. 11, 2012.

"They took you and mommy away from us-but they shall suffer-God never lies. I promise you my little one- I will fight for you both to the very end. God has my back and my eyes wide open-He knows I am fighting in that devils den," she wrote. "But like I said, don’t you worry-we will surely get them all. From those who sit up high-to that very evil one who made the last call. See, every man has his day-this is something they must of forgot. They cannot run nor can they hide. They took the wrong ones on my watch!"

Leolah’s comments comes after the Fulton County, Georgia, medical examiner unsealed the aspiring actress’ autopsy reports. In a statement Friday, the medical examiner said alcohol, prescription drugs and marijuana were contributing factors in Bobbi Kristina’s death. The medical examiner also determined that the cause of death was “lobar pneumonia.”

"Due to: hypoxic ischemic encephalopathy, delayed effects. Due to: immersion of face in water complicating mixed drug intoxication,” the statement read (via People magazine).

In September, Leolah told “Inside Edition” that she would never believe Bobbi Kristina’s death was an accident. Instead, she accused her niece’s then-boyfriend Nick Gordon of murdering her. Gordon has never been arrested or charged with any crime related to Bobbi Kristina’s death, and he has said numerous times he was not involved.
