The cause of Bobbi Kristina's death has been determined, however authorities in Georgia will not be making the information public while a criminal investigation into her death is ongoing. According to TMZ, a judge has ordered that the Fulton County Medical Examiner's conclusion about how the 22-year-old died must remain sealed, to prevent the findings hindering their inquiries.

The daughter of Whitney Houston and Bobby Brown died on 26 July at Atlanta's Peachtree Christian Hospice, almost six months after she was found unconscious in a bathtub at her home in Georgia in tragically similar circumstances to her mother who died three years earlier. She was buried next to her mother, at Fairview Cemetery in Westfield, New Jersey, on 3 August.

Earlier, the medical examiner said the time that elapsed from when Ms Brown was found unresponsive until her death would "complicate" its effort to reconstruct events.The incident was described as a "drowning" by police, and doctors said Brown had suffered irreversible brain damage.

Bobbi Kristina's partner, Nick Gordon, who found her face down and unresponsive in the bath has been the focus of an investigation by law enforcement in Fulton County.

In June, Bobbi Kristina's conservator Bedelia C. Hargrove filed a $10m (£6.4m) lawsuit against Gordon alleging that he stole money from her and subjected her to domestic abuse. Legal documents stated on 17 August that he murdered the reality star by giving her a "toxic cocktail" of drugs before putting her face-down in the bathtub at their Georgia home.

Gordon's lawyers filed a response on Tuesday 6 September to an amended complaint filed last month in a civil lawsuit vehemently denying the allegations of assault, battery, causing emotional distress and theft describing the claims as 'slanderous and meritless', according to People.

Gordon is reported to have claimed that he had tried to resuscitate Bobbi Kristina but was unsuccessful. He added that 'others unsuccessfully attempted to resuscitate Ms. Brown'. He denied allegations of fraud, and that he had married' her or tried to 'control' and 'limit' her interactions with others so that he could benefit from her wealth. No criminal charges have been brought against Nick Gordon.

Bobbi Kristina was the sole heir of her mother Whitney's Houston's £22 million fortune. Nick Gordon was welcomed into the Houston family aged 12, after his father went to prison. He was brought up as Bobbi Kristina's brother, but the pair later announced they were "married"

Bobbi Kristina's father Bobby Brown opened up about her tragic passing during his first interview since her death. Appearing on talk show The Real earlier this month, he said: "We prayed in hope for six months, you know, for something better to happen, but when God calls you, He calls you."
