Bobbi Kristina's Cause of Death is Finally Revealed

Eight months after Bobbi Kristina Brown passed away, her cause of death has finally been revealed.

Eight months after Bobbi Kristina Brown passed away, her cause of death has finally been revealed.

The 22-year-old's cause of death was lobar pneumonia due to "immersion of face in water complicating mixed drug intoxication," according to a statement from the Fulton County Medical Examiner's office on Friday morning.

The daughter of Whitney Houston and Bobby Brown was found face-down and unconscious in her bathtub in her Atlanta home in January 2015. She passed away while in hospice care in July last year.

The medical examiner's office reviewed medical records, investigative files and other documents to determine how she likely died.

It said that the drugs involved in her death included marijuana, alcohol, medications used for sedation or to treat anxiety, and morphine.

"It could not be determined from toxicology tests whether the morphine resulted from heroin use," the statement said.

"The underlying cause of death is the condition which starts the downhill course of events leading to death and in this case is the immersion associated with drug intoxication," it said.

The statement from the medical examiner's office was released a day after a superior court judge granted a motion to unseal the autopsy.

It added that while her death was clearly not due to natural causes, the medical examiner was unable to determine if the death was intentional or accidental. It has been classifed as undetermined.

Brown's aunt Leolah told INSIDE EDITION that year that she believes her niece was murdered.

“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. I don't know who actually murdered Whitney."

She said that she believes Brown's boyfriend, Nick Gordon, was to blame. But he has never been arrested or charged in connection with her death and has denied any wrongdoing.

Brown's mother, Whitney Houston, died in similar circumstances in 2012. She was found face-down in her bathtub at the Beverly Hilton Hotel just before the Grammy Awards. Her death was determined to be accidental drowning.
