Bobbi Kristina Brown was hospitalized for nearly six months following a Jan. 31 medical emergency. After spending her final days in hospice care, she died on Sunday.

The Fulton County Medical Examiner's office had the sad and challenging task of performing an autopsy, and has announced that the procedure found no obvious cause of death, the Associated Press reported. Bobbi Kristina, the only child of the late Whitney Houston and singer Bobby Brown, was 22.

The lawsuit, filed last month in Fulton County Superior Court, claims that Gordon harmed Bobbi Kristina physically, wrested control over her finances and had taken money from her during the time she had been hospitalized since being found unresponsive in a bathtub on Jan. 31.

The suit claims Gordon “caused, among other things, substantial bodily harm” to Bobbi Kristina. Gordon's lawyers declined to comment.
