Bobbi Kristina Brown: Dad Accuses Nick Gordon Of Cover-Up!

Bobby Brown says that the death of Bobbi Kristina Brown is "not a mystery to me" — as he suggests that her boyfriend Nick Gordon is to blame for the death of his daughter, and even that of Whitney Houston! "The same thing that happened to my daughter is what happened to Whitney," declared the grieving father (seen here at Bobbi Kristina's funeral). "There’s only one person that was around both occasions, only one person who says they were there to protect them — and he didn’t!"

Bobby, who refused to even utter Nick's name while talking to ABC News, has also joined the wrongful death suit filed against Nick in the wake of The National ENQUIRER's bombshell reporting on Bobbi Kristina's mysterious death. She was first found unresponsive in a bathtub in January 2015, and died in hospice care six months later at the age of 22. The drug-filled body of Whitney, 48, was found dead at a Beverly Hills hotel in February 2012 — also in a bathtub.

The ENQUIRER revealed the dark secrets of Bobbi Kristina's final tormented days — publishing shocking exclusive photos of Whitney's daughter following the diva's drug-crazed path. Insiders claimed that Nick had enabled her drug-crazed lifestyle. And the ENQUIRER's experts agree with Bobby Brown that the deaths of Bobbi Kristina and her mother should both be investigated!

“This smacks of a double cover-up!” former Secret Service agent John A. Carman told The ENQUIRER. “Whitney Houston ends up dead in a bathtub, covered with bruises, under hinky circumstances Three years later, [Bobbi Kristina] dies in a bathtub, also covered with bruises, under hinky circumstances.”

The autopsy report on Bobbi Kristina also gave a huge boost to the $40 million civil suit filed by her conservators against Nick (seen here at Bobbi Kristina's grave in New Jersey). The suit alleges that Nick, 25, had battered the daughter of Whitney Houston — and then plied her with drugs before she was found unconscious in a water-filled bathtub.

The 10-page document from the Medical Examiner, obtained by The ENQUIRER, revealed Bobbi Kristina had bruises on her arms and thighs, plus dozens of “well-healed scars on the head and neck, torso and extremities.”

A toxicology report on Bobbi Kristina's system revealed the use of marijuana, alcohol, “a cocaine-related substance,” morphine and anti-anxiety medications. “The toxicology report backs up the charges in the civil suit," said Paul Huebl, a former Chicago cop who's now a Hollywood private eye.

“While the report couldn’t definitively determine Bobbi Kristina was murdered," added Paul, "Nick is not off the hook for her death. A civil trial is already scheduled, and now there may be criminal charges against him, too!”
