Randy Kessler, an attorney for Gordon, said he was not surprised by the findings.
The medical examiner didn’t find really high levels of any drug, and the combination of drugs found in her system is not unusual, said Dr. Paul Wax, a professor of emergency medicine at the University of Texas Southwestern Medical Center who reviewed the autopsy report at the request of The Associated Press.
“She’d used a bunch of drugs, she went into the bath and she basically drowned in the bathtub,” he said. “That’s pretty much all you can tell from this report.”
She likely used the drugs within 24 to 48 hours before she entered the bathtub, but it’s not possible to say when she took each one or whether multiple drugs were taken at the same time, Wax said.
The Fulton County Medical Examiner’s office in Atlanta said it reviewed medical records, investigative files and other documents in producing its report. Marijuana and medications used for sedation or to treat anxiety were also found in her blood.
“It could not be determined from toxicology tests whether the morphine resulted from heroin use,” the medical examiner’s statement said.
“The underlying cause of death is the condition which starts the downhill course of events leading to death and in this case is the immersion associated with drug intoxication,” the medical examiner’s office 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,” the statement says.
A judge on Thursday had granted a request filed by media organizations to unseal the autopsy.
“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,” her father, Bobby Brown, said in a statement released by his attorney.
Fulton County District Attorney Paul Howard said in a statement Thursday that his office is still investigating.
Bobby Brown also noted that Friday is his late daughter’s birthday.
“First and foremost, 23 years ago today, Bobbi Kristina was born. Krissy will always live in my heart and soul. I love my baby girl,” Bobby Brown said.
Brown’s death was similar to the way her mother died.
Whitney Houston’s body was found face-down in a foot of water in her bathtub at the Beverly Hilton Hotel just before the 2012 Grammy Awards. Authorities found prescription drugs in the suite and evidence of heart disease and cocaine in Houston’s body and determined her death was an accidental drowning.
Bobbi Kristina Brown was found in the townhome she shared with Gordon, an orphan three years older whom Houston had raised as her own. Brown referred to him as her husband.
Brown grew up in the shadow of her famous parents. She appeared with them in 2005 on the Bravo reality show “Being Bobby Brown” and attended award shows with her mother and father.
Houston and Bobby Brown were married 15 years before their relationship ended in 2007. Bobbi Kristina was their only child together.
