ATLANTA (AP) - R&B singer Bobby Brown said Monday that his daughter, Bobbi Kristina Brown, was "an angel" and that the family must find a way to honor her memory.
Bobbi Kristina, the daughter of singer Whitney Houston, died Sunday in hospice care, six months after she was found face-down in a bathtub in her suburban Atlanta townhome. Authorities are investigating her death.
"Krissy was and is an angel," her father said in a statement. "I am completely numb at this time. My family must find a way to live with her in spirit and honor her memory. Our loss is unimaginable."
Bobbi Kristina had been hospitalized for months in Atlanta - eventually being placed in hospice care - after being found in a manner grimly similar to the way her megastar mother died three years earlier.
A police report earlier this year described the incident as a drowning. In a statement Monday, the Fulton County Medical Examiner's Office said an autopsy will be needed to evaluate what led to the death of Bobbi Kristina, but the time that has elapsed since the autopsy will complicate the investigation. The medical examiner did not release a timeframe for the autopsy, but said additional lab testing might take several weeks.
"Interpretation of autopsy findings and other information will also be challenging," the medical examiner's office said. "However, an autopsy could be helpful to address questions which may arise about the cause of her unresponsiveness and eventual death."
