It was supposed to be a special holiday season for a 3-year-old Kailua girl, but her family now mourns her passing.
Thirty-two days after visiting a dentist, Finley Boyle died Friday night, never recovering consciousness.

Finley passed away just before 9 o'clock, surrounded by her parents and family members at Hawaii Hospice in Kailua.
"To see her grow from a happy healthy 3-year-old to going through puberty in a diaper 15 years later is not a choice I was going to make," said Ashley Boyle, Finley's mother.
"She was in a persistent vegetative state. They felt that this is what she would want as difficult as it was. They felt that was the right choice," said attorney Richard Fried Jr.
Fried said Dr. Lilly Geyer with Island Dentistry for Children made many wrong choices on Dec. 3. Finley went in for a dentist appointment and she left with permanent brain damage.
"It's very sad. It's their only child. It's totally unnecessary. This was a perfectly normal, healthy, maybe unusually bright, full-of-life child," said Fried.
He says Finley was getting 10 different procedures, four which were a type of root canal. And says she was given five drugs in very excessive doses, and adding to the problem, she wasn't monitored throughout the procedure.
"Clearly once we got the second MRI back, it was devastating. Everything but the brain stem, which the brain stem tells you to breathe and gives you a brain pressure, that was the last bit that didn't get a lack of oxygen," said Boyle.
Lawyers said someone from the dentist office had to run down the hall to get a pediatrician to revive her.
By then it was too late.
A wrongful death lawsuit was filed by the family.
KITV4 tried to contact Dr. Geyer's attorney for comment, but wasn't able to reach him. Her Island Dentistry for Children has since been closed.
