The mother of a 14-year-old girl with cerebral palsy who weighed 28 pounds when she died has been sentenced to nine years in prison.

Angela Norman, 43, was sentenced in a Dayton, Ohio court on Thursday after pleading guilty to involuntary manslaughter.

Her daughter Makayla Norman was covered in bed sores and showed other signs of neglect when she died on March 1, 2011, said court authorities.

The county coroner’s office attributed the teen's death to nutritional and medical neglect complicated by her chronic condition.

'She was the worst malnourished child this office has ever seen,' said Ken Betz, director of the coroner's office.

Three nurses who authorities said were to administer or monitor the girl's care also were charged.
