KAILUA, OAHU (HawaiiNewsNow) - Gathered outside Castle Medical Center on Wednesday night, Ashley Grey's friends and family stood hand in hand and prayed for a miracle.
The 30-year-old was rushed to the emergency room early Sunday. Prison officials say she was found alone and unconscious in a cell at the Women's Community Correctional Center in Kailua.
Police told family Grey hanged herself and an internal investigation ruled out foul play. But Grey's mother says it looks like someone beat her.
"She had a big black eye right here on the right side and then she had a big gash and a busted lip," said Grey's mother, Saresa Manu.
"As of this morning, she's brain-dead. There's no activity. There's nothing. She's gone."
A video obtained by HNN shows Grey's injuries along with bruises around her ankles and a gash on her leg.
Prisoners rights advocate Kat Brady questions how she got a mark on her neck.
"They say she hung herself. I've never seen anything like this. It's a very, very thin line that's dried blood," Brady said.
And it's not just the physical injuries that are raising suspicion.
Manu says the last time she went to visit her daughter, Grey told her she didn't feel safe.
"She said don't ask any questions because I can't give you the answer," said Manu. "I know as a mother my daughter would never ever, wouldn't even think about taking her own life."
Grey was serving time for probation violations on a 2009 drug conviction and was scheduled to be released on parole later this year.
Brady says one of Grey's last known interactions was with a teacher inside a prison.
"She said Ashley was positive. The class was really focused on Ashley's restorative circle because she was coming home and she was excited to see her mom and daughter again, so she was shocked this happened," Brady said.
Grey will be taken off life support after her daughter arrives from the mainland to say goodbye.
