Bobbi Kristina Brown’s face was immersed in water and she was intoxicated with a mix of marijuana, alcohol, morphine and other drugs — both conditions that caused pneumonia that led to her death, a medical examiner said in a statement released Friday morning.

The 22-year-old daughter of singers Whitney Houston and Bobby Brown was found face-down and unresponsive in a bathtub in her suburban Atlanta townhome Jan. 31, 2015, and died in hospice care July 26.

The Fulton County Medical Examiner’s office in Atlanta said it reviewed medical records, investigative files and other documents to determine how Brown likely died. Marijuana and alcohol were involved in the death, along with medications used for sedation or to treat anxiety, the medical examiner’s office said.

“The underlying cause of death is based substantially on review of medical records, the results of toxicology tests, investigative records, and the fact that the autopsy did not show any other likely underlying cause of death or reason for Ms. Brown becoming unresponsive.,” the medical examiner’s office said in the statement.

It wasn’t possible to determine whether her death was accidental or intentional, the medical examiner’s office said.

“Death was clearly not due to natural causes, but the medical examiner has not been able to determine whether death was due to intentional or accidental causes, and has therefore classified the manner of death as Undetermined.”
