Amid reports police in Georgia are pursuing a possible criminal investigation regarding the death of Bobbi Kristina Brown, daughter of the late singer Whitney Houston, it is instructive to recall Brown’s aunt warned immediately after Houston’s death three years ago that Bobby Kristina was “not safe.”

And the aunt, Leolah Brown, sister of Houston’s husband, R&B singer Bobby Brown, posted a cryptic message on her Facebook page Sunday about her niece’s death.

Bobbi Kristina Brown died in hospice care Sunday, five months after being found unresponsive in a bathtub and placed in a medically induced coma. Her body reportedly suffered bruising.

The conditions were eerily similar to the death of Houston, who was found dead in the bathtub of her guest room at the Beverly Hilton Hotel in Beverly Hills, California.

Immediately after Brown was found in the tub in June, Georgia police opened an investigation. Some reports said the focus was on Brown’s boyfriend, Nick Gordon, who administered CPR while a friend who discovered Brown’s body in the tub called 9-1-1.

Four weeks ago, while Brown was still alive, District Attorney Paul Howard released a statement to the media saying his office would be looking at the case with “greater interest.”

“The Roswell Police Department has forwarded its investigative file to our Office,” he said. “In view of the new circumstances regarding the health status of Bobbi Kristina Brown, we will be reviewing the case with greater interest.

“An announcement regarding a charging decision, if any, will be made at the appropriate time.”

Sunday, Bobbi Kristina’s aunt, Leolah Brown, posted a cryptic message on her Facebook page with no further explanation.

“Today (2015) is a day that we fight … and fight hard … by any means necessary … For, we are obliged … and it is ordained by God Himself,” she wrote.

Largely forgotten by the media is that in an ominous interview 17 days after Whitney Houston’s death on Feb. 11, 2012, Leolah Brown warned her niece was in danger.

“I am concerned about my niece Bobbi Kristina, yes,” Leolah told the television show “Access Hollywood” at the time, referring to Kristina Brown as “Krissy.”

“Krissy is not safe right now,” she said. “I want to say to Krissy that it’s very, very, very important that she does not trust anybody at this time. Anybody except her father, her grandmother Cissy and myself. And I mean that.”

Leolah Brown did not elaborate on the purported threat faced by her niece other than to say, “Right now is the time to just really shut the door.”

Leolah’s attorney, Reginald Mason, was also unspecific about who may try to harm Brown.

“There are persons that possibly would want to take advantage of Bobbi Kristina’s fragile state of mind,” Mason claimed at the time.

Leolah further claimed: “I believe Whitney’s death was not accidental. No.”

Asked who or what then killed Houston, Leolah replied: “My attorney has advised me not to get into that at all. But, it’s very important to know that she did not just pass away like that. No. And if it’s the last thing that I do, I’m going to find out what truly happened to my sister.”
