A six-year-old girl is clinging to life after suffering critical head injuries two weeks ago. Honolulu Police have opened an assault case but there have been no arrests. The state has removed the girl's two siblings from their home. It is a case that may have gone un-noticed by most if it wasn't for a phone call to the girl's former foster mother.

For three years Beverly Hawver and her husband Scott were foster parents to Nellie raising her in their Ewa Beach home.

"She was 15 months and she was 18 pounds. She couldn't walk she didn't really talk, she said two words," Hawver said in a 2005 interview.

In 2005 when the state renewed its focus on birth family visits, Nellie started seeing her biological mother.

"Sleepless nights, I mean just screaming not being able to sleep," she said. "We kept telling them you know she's regressing -- she ended up back in diapers."

As visits increased her behavior changed.

"She came home one afternoon from her visit was on the back of my couch -- took her panties off," said Hawver. "They kept pushing, they kept pushing the social worker kept pushing."

In March 2006 Nellie returned to her mother's custody and the Hawver's relocated part-time to Texas.

"We didn't know what was going to happen but we knew something was going to happen," said Hawver.

Sunday night, Beverly received a call saying Nellie was in the hospital. She returned to Hawaii Monday.

"She was close to death and that they were going to pull life-support and that her situation is critical -- it's just critical. She has severe head injuries, a part of her skull was removed and part of her frontal lobe. Now I'm asking the state is it going to be covered up again?"

Police say the girl's mother has been interviewed. The state said in a statement: Honolulu police officers and the Department of Human Services are conducting a thorough investigation of this tragic case to uncover all the facts surrounding the girl's injuries.

"It's time to stand up - it really is time this nonsense with these children being returned to parents that are not capable of taking care of their children just because there's a kinship policy may not always be the best interest of the child," said Hawver who wants to see Nellie and hold her again. "It doesn't matter who inflicted the injury -- that's not even the point -- the point is she's in the hospital and there was no one there to protect her."

Koller says her office will release all the information it can under federal and state laws.
