A medical examiner's office releases information Friday after a judge's ruling

Bobbi Kristina Brown's autopsy results were sealed under a court order

The daughter of pop icon Whitney Houston was found unresponsive in a bathtub

Atlanta CNN  — 

Drug intoxication and immersion in a bathtub of water led to Bobbi Kristina Brown’s death months later from pneumonia and brain damage, a Georgia medical examiner said Friday after a judge allowed him to release the findings.

The Fulton County Medical Examiner’s Office said it could not say whether the 2015 death of pop icon Whitney Houston’s daughter was an accident - or something else.

Emergency crews found Brown unresponsive in her suburban Atlanta home in January 2015, and she died at a hospice in July at age 22, having never regained consciousness.

The medical examiner’s office said it found several drugs in Brown’s system, including marijuana, alcohol, a cocaine byproduct, medications that sedate people and treat anxiety and morphine. The office said it couldn’t tell whether the morphine was a sign of heroin use. Heroin metabolizes to morphine.

The findings – released on what would have been her 23rd birthday – strengthen an eerie link between the deaths of Brown and her pop icon mother three years earlier.

Whitney Houston, in 2012, was found dead face-down in a tub of water – a death ruled as an accidental drowning, complicated by cocaine use.

Brown’s father, singer Bobby Brown, expressed displeasure at Friday’s release of his daughter’s autopsy information.

“First and foremost, 23 years ago today, Bobbi Kristina was born. Krissy will always live in my heart and soul,” Bobby Brown said in a statement released by his lawyer. “I love my baby girl.

“For news affiliates to seek and obtain my daughter’s autopsy report, before anyone has been brought to justice for her death is mind-blowing to me. Please pray for my family.”

Authorities in Georgia have always maintained they long knew how Brown died, but they declined to release details because of a superior court’s order to seal the autopsy information.

That changed this week after a judge in Atlanta granted a request by local media to unseal her autopsy results.

Judge Henry Newkirk, who granted the motion, said he doesn’t “think there is anything particularly earth-shattering in the report,” CNN affiliate WGCL reported.

Wrongful death lawsuit

The 22-year-old was found January 31 in an eerily similar manner to how her music legend mother was discovered dead three years before: facedown and unresponsive in a bathtub full of water.

Brown’s estate has filed a $10 million wrongful death lawsuit against Gordon, alleging he beat her after an all-night “cocaine and drinking binge,” before giving her a “toxic cocktail” that knocked her out, according to the suit.

Gordon has never been charged in relation to Brown’s death, and his legal team called the lawsuit “slanderous and meritless.”

In his first public remarks since his daughter’s death, Bobby Brown said in a talk show appearance this month that he is creating a center for victims of domestic violence in Bobbi Kistina’s memory.
