An autopsy is needed to establish what caused the death of Bobbi Kristina Brown, the daughter of the late Whitney Houston.

Bobbi Kristina was found unresponsive in a bath tub seven months ago at the home she shared with her boyfriend Nick Gordon in Atlanta. She never regained consciousness and died at the Peachtree Christian Hospice in Duluth, Georgia on Sunday.

The Fulton County Medical Examiner's Office said the time that elapsed from when she was found unresponsive in January until her death will "complicate" its effort to reconstruct the events before and after she was found unconcious.

“Despite the long interval between her being found unresponsive and her death, an autopsy will still be necessary to further evaluate possible causes of death or contributing factors,” it said in a statement.

"Interpretation of autopsy findings and other information will also be challenging. However, an autopsy could be helpful to address questions which may arise about the cause of her unresponsiveness and eventual death."

The statement added: "The Roswell Police Department continues its investigation into the circumstances preceding and surrounding the time of the original incident leading to her death.”

Gordon said Bobbi Kristina wasn’t breathing and he couldn’t find a pulse before emergency services arrived. The incident was described in a police report as drowning.

Gordon was informally adopted by Houston in 2002 and grew up in the family home, but he began dating Bobbi Kristina shortly after the singer's death.
