A medical examiner investigating the death of Bobbi Kristina Brown say it's unclear if her death was accidental or intentional.
Before her death in July, Brown spent months in a coma after being found unresponsive in a bathtub in her north Atlanta home last year.
The autopsy for Brown, the 22-year-old daughter of singers Whitney Houston and Bobby Brown, confirmed yesterday that drugs and the immersion of her face in the water led to brain damage and pneumonia, which was ruled as the official cause of death.
