London: Bobbi Kristina Brown's husband Nick Gordon will be questioned by the cops in regard to her suicide attempt after she was found face down in a bath at her home in Atlanta.
Kristina's family said that she had been living apart from her 23-year-old husband after their marriage became increasingly troubled, the Mirror reported.
Investigators have not ruled out that drugs may have played a part in the drama as they did not find anything substantial after an initial search of the couple's home.
Police also want to know how much time there was between Kristina falling unconscious to her being found and paramedics being called.
Kristina's late mother Whitney Houston was found accidentally drowned in a hotel bath aged 48 with her face down.
