The hospitalization of Bobbi Kristina Brown is taking an interesting turn, as investigators seem to believe others were at the home Jan. 31, the morning she was found unresponsive and face down in her bathtub.

If this is the case, then it could prove that some form of illegal activity was taking place at the home, and it could be the reason for Bobbi Kristina, 21, being in the state she is now.

Detectives at the Roswell Police Department are playing with the idea that before the arrival of the police, one or two other persons may have fled the scene. The officers have interviewed several store owners in the Ellard Village mall adjacent from where Bobbi Kristina resides.

They were asked whether they saw any suspicious activity on Saturday prior to the officers arriving at Bobbi Kristina's house.

We understand that at least two police officers have visited Sun Trust Bank on Holcomb Bridge Road after the incident involving Whitney Houston and Bobby Brown's daughter occurred. It is not entirely clear what they have found, or if they are seeking anyone.

"[Police] were asking if they saw anyone jump the wall behind the house, or if anyone was seen leaving the area," according to a source who spoke with E! News. "But no one recalled seeing anyone or anything suspicious. But the cops also were looking for video."

It would be very interesting should police officers find out that others apart from Bobbi Kristina's boyfriend, Nick Gordon, and their friend Max Lomas was at the apartment. It would mean that both men probably lied to police, and it could get them in deep trouble.

Already, the boyfriend Gordon is unable to visit Bobbi since the family filed a restraining order against him. He will only get the chance to visit her should the family be away from the hospital. We doubt that is going to happen anytime soon, so his situation is quite messy.

Furthermore, it was said Bobbi Kristina and Nick Gordon were married, but Bobby Brown released a statement claiming this is not the truth. He and the family believe Gordon is only interested in Bobbi Kristina's inheritance, although she will not get the chance to touch it until she is 35.
