UPDATE: Bobbi Kristina Brown Suffered 'Unexplained Injuries'

The Hollywood Reporter writes that investigators are still looking into the unexplained injuries found on Whitney Houston and Bobby Brown's 21-year-old daughter Bobbi Kristina Brown, after she was found facedown and unresponsive in a bathtub full of water at her Roswell, Georgia, home on January 31.

Brown is reportedly in a medically induced coma at Emory University Hospital. According to USA Today, Whitney Houston's mother, Cissy, has visited her there.

Earlier last week, FOX News reported that there is little that doctors can now do to save Bobbi's life.

A source closely connected to the situation told FOX411, "It's now a matter of when the family wants to let go and accept that she's pretty much not going to make it," adding that doctors have expressed that there is little they can do. "They've left it up to the family as to how long they want to keep her alive."

The incident transpired almost three years after her mother was found dead in a bathtub in Beverly Hills.

"It's been a difficult time for Bobbi Kristina, who's struggled in the years after her mother's death," said an unnamed source close to the family. Brown "has been vacillating between extremes for a while now and is fighting grief and demons of her own creation," the source said. "The loss of her mom and her intense craving for attention of any sort are just the tip of her mountain of issues."
