New details have emerged in Bobbi Kristina Brown's tragic accident, and E! News reports that Roswell Police Department detectives are now investigating the possibility that another person may have been in Bobbi Kristina's home when she was found face down in a bathtub by partner Nick Gordon.

And yes, that's the other update -- Bobbi Kristina's dad Bobby Brown released a statement and noted that his daughter was NOT actually married to Gordon. "We are currently investigating the events that led to the hospitalization of Bobbi Kristina," Brown told E! News on Tuesday. "To correct earlier reports, Bobbi Kristina is not and has never been married to Nick Gordon."

Two police investigators reportedly visited Sun Trust Bank, which is about 100 yards from Bobbi Kristina's residence, and questioned employees and asked for parking lot surveillance video. "[Police] were asking if they saw anyone jump the wall behind the house, or if anyone was seen leaving the area," a source tells E! News. "But no one recalled seeing anyone or anything suspicious. But the cops also were looking for video."

Brown and Gordon's pal Max Lomas was also inside the home at the time she was discovered. She's currently under a medically induced coma, and a rep for the family said in a statement yesterday, "Bobbi Kristina is fighting for her life and is surrounded by immediate family. As her father already stated, we are asking you to honor our request for privacy during this difficult time."
