– Murky circumstances –
Bobbi Kristina’s parents separated in 2006 and divorced in 2007, with Houston awarded custody of their daughter, amid claims of abuse and drug use in the high-profile relationship.
They were by all accounts extremely close, with Bobbi Kristina accompanying her mother to events and awards shows.
Her parents appeared in a 2005 reality show “Being Bobby Brown” that shed some light on their personal struggles and family challenges.
After her mother’s death, Bobbi Kristina – who had hoped to follow in Houston’s footsteps as a singer – and several relatives appeared in another reality show, discussing their grieving and working on picking up the pieces.
A final coroner’s report said Houston may have overdosed on drugs and alcohol before drowning, and that drug-related heart damage played a part in her death.
The circumstances that led to Bobbi Kristina being pulled unconscious from a bathtub are similarly murky.
In February, US media reported that police had opened a criminal probe into Bobbi Kristina’s boyfriend Nick Gordon, who reportedly said that it was he who found her in the bathtub.
The reports said that Bobbi Kristina sustained unexplained injuries prior to the incident, while there are also claims of a drug overdose, but no criminal charges have been brought.
Gordon spent years being raised by Houston in her home and grew up alongside Bobbi Kristina, although he was never formally adopted by the pop singer.
He and Bobbi Kristina revealed their romantic relationship after her mother’s death.
