Bobbi Kristina Brown's Cause of Death Revealed

Bobbi Kristina Brown‘s official cause of death has been revealed over a year after she was found submerged in a bathtub.

The daughter of Whitney Houston, who died in 2012 from drowning, also died from drowning and from doing drugs. She was taken off life support on July 26.

“Immersion of face in water complicating mixed drug intoxication,” is the official cause of death listed on the Fulton County Medical Examiner’s testing. Drugs that were found in her system include “marijuana, alcohol, a cocaine-related substance called benzoylecgonine, benzodiazepines (prescription anti-anxiety meds) and morphine,” according to TMZ.

It is not known if there was foul play involved, though there is an ongoing investigation into Bobbi‘s boyfriend Nick Gordon‘s possible involvement in her death.
