Bobbi Kristina died from Immersion of face in water complicating mixed drug intoxication.

The late Whitney Houston's daughter Bobbi Kristina died of drug complications and face immersion in water according to the coroner who investigated the case.

According to various media publications attributed to the coroner, this is how he explained the death.

The drugs involved included marijuana, alcohol (ethanol), benzoylecgonine (a cocaine-related substance), benzodiazepines (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 other question which arises is manner of death. In other words, did death result from natural causes such as disease, an intentional act such as suicide or homicide, an unintentional cause (accident), or in an undetermined manner when a more specific manner of death cannot be established.”
