ATLANTA: Bobbi Kristina Brown died as a result of immersion in water and drug intoxication, medical records show.

The 22-year-old daughter of singer Whitney Houston 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 released an initial statement ahead of the full post-mortem report — eight months after her death.

The medical examiner’s office said it reviewed medical records, investigative files and other documents to determine how Brown died.

The exam concluded cannabis and alcohol were involved in her death, along with medication used for sedation or to treat anxiety, citing the “underlying cause” of death as “immersion associated with drug intoxication.”

The statement 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.”

A judge in Atlanta had issued an order to unseal the autopsy report for Brown. Fulton County Superior Court Judge Henry Newkirk on Thursday granted a motion filed by media organizations. Media lawyers argued the September sealing order violated the state and federal constitutions and court rules because there was no public notification or opportunity for a hearing. The state argued the law exempts records sealed by court order. Fulton County District Attorney Paul Howard said in a statement he believes the records should remain sealed but that he will follow the instructions of the court.
