Bobbi Kristina Houston, daughter of Whitney Houston is in a medically-induced coma after she was found face down a bathtub in her home in Roswell, Georgia, just days before the anniversary of her mother’s death.

According to the Atlanta Constitution, “The investigation is widening and may be focused on more than one person.” But, no one has been charged in connection to the investigation. TMZ has reported earlier this week that the police were investigating Bobbi Kristina’s relationship with Nick Gordon, who she had said was her husband, but they are actually not legally married.

Gordon has a lawyer and hasn’t spoken publicly since Bobbi was found by a friend Maxwell Lomas, according to the Boston Globe. Lomas had called 911 while Gordon is said to have administered CPR.

Gordon has a rough relationship with both sides of Bobbi Kristina’s family, and it was reported that Gordon got into a shoving match with her father in her hospital room. Bobbi was transferred to Emory University, where she remains. Some reports now say Bobbi Kristina’s relationship with Gordon was sometimes violent.

An unidentified family member told People magazine in 2012 that Gordon is one of the only people who can actually get through to her sometimes and he sometimes uses that to his advantage.

More questions will continue to emerge until police and family members figure out what actually happened to Bobbi Kristina.
