Autopsy: Still unclear if Bobbi Kristina’s death was accidental ATLANTA — An autopsy determined Bobbi Kristina Brown had a mix of drugs in her body when she went underwater in a bathtub, but a medical examiner couldn’t tell whether her death was a homicide, making the criminal investigation tougher. The medical examiner’s report released Friday showed that Brown, the daughter of singers Whitney Houston and Bobby Brown, had morphine, cocaine, alcohol and prescription drugs in her body.
