Bobbi Kristina Brown‘s autopsy revealed that she died of a combination of drugs, alcohol and drowning.

Bobbi Kristina Autopsy

The Fulton County Medical Examiner determined that Bobbi Kristina, the daughter of Bobby Brown and the late Whitney Houston, died from “immersion of face in water complicating mixed drug intoxication,” reported TMZ. In addition to alcohol, there was also marijuana, morphine (possibly related to heroin), benzoylecgonine (related to cocaine) and benzodiazepines (anti-anxiety medication) found in Bobbi Kristina’s system.

Bobbi Kristina’s official cause of death is listed as pneumonia and encephalopathy. As a result of her drowning, her lungs had filled with water, and she suffered brain damage.

The ME was unable to confirm whether Bobbi Kristina’s death was “due to intentional or accidental causes.”

Bobbi Kristina’s surviving boyfriend Nick Gordon has been under investigation for involvement in her death. While the ME’s findings could clear him of criminal charges, he is still facing a wrongful death lawsuit filed by Bobbi Kristina’s estate. The estate is alleging that Gordon gave Bobbi Kristina the lethal mix of substances that led to her death, and is seeking $40 million in damages.

Bobbi Kristina was found unresponsive in the bathtub of her Atlanta-area home on Jan. 31, 2015. She remained on life support in hospice care in Georgia until July 26, when she was pronounced dead aged 22.
