It was Bobbi Kristina Brown's facial injuries that made police start a criminal investigation.
According to the reports, the 21-year-old singer had suffered injuries to her face, specifically her mouth, before she was found face down in a bathtub and the authorities are now focusing on her boyfriend Nick Gordon regarding the same, TMZ.com reported.
Roswell PD had already started looking closely into Kristina's relationship with Gordon, as sources have claimed that there was also a history of violence, in addition to their friend Max Lomas claiming that Gordon was acting strangely before they found her.
