Bobbi Kristina Brown died of complications from drugs, immersion

ATLANTA, March 4 (UPI) -- Bobbi Kristina Brown's death was caused by complications related to drugs and immersion in water, according to autopsy information released Friday.

About seven months since the 22-year-old's official death at a hospice facility in July, Brown's autopsy results were unsealed after an Atlanta judge granted local media's request for its release.

On Thursday, the Fulton County Medical Examiner issued a statement naming Brown's official cause of death as lobar pneumonia, which was directly caused by intoxication and immersion.

Drugs found in Whitney Houston's daughter's system included marijuana, alcohol, a cocaine-related substance, anxiety medicine and morphine. "It could not be determined from toxicology tests whether the morphine resulted from heroin use," the statement read.

The manner of death is officially undetermined, as it is still unclear whether Brown's demise resulted from natural, intentional or accidental methods.

Bobbi Kristina Brown died at age 22 six months after being found unconscious in a bathtub of water. She never regained consciousness.
