Bobbi Kristina moved to Emory University Hospital

DEKALB COUNTY, Ga. — New doctors are treating Whitney Houston’s daughter Bobbi Kristina Brown.

Brown is on life support at Emory University Hospital. She was transferred there Tuesday after several days in North Fulton Hospital.

Emory University has one of the top-ranked neuro intensive care units in the country.

“I think it's a really a sad situation. I think she's still in deep grief. I think she just couldn't handle her mother being gone,” said Barbara Wright, who lives in Roswell.

The 21-year-old was found by her husband and a friend face-down in a bathtub in their Roswell home on Saturday.

“I'm sure that being an only child has got to be devastating. I'm sure she just never really got over it. Who does,” said Wright.

The family issued a statement saying Bobbi Kristina is fighting for her life.  She's been on a ventilator after being found unconscious.

Emory University Hospital’s Neuro Intensive Care Unit has more than 135 doctors using groundbreaking treatments resulting in unexpected solutions, according to their website.

It was three years ago that singing superstar Whitney Houston was found dead in a bathtub in California.

A tweet sent on Bobbi Kristina's Twitter page five days before she was found in the tub said, “Miss you mommy, so much. Loving you more every second. #anniversary.”
