A suburban South Carolina mother who admitted burning down four homes near her neighborhood has been sentenced to more than a decade in prison.

Kimberly Wooten was sentenced to 15 years in prison Monday. Two of those years have been suspended by a judge and she also received credit for time served.

The 42-year-old mother of two pleaded guilty but mentally ill in June to seven counts of second-degree arson and other charges related to the fires.

Wooten’s attorney says she had an irresistible impulse to start fires. Her plea meant she knew right from wrong, but couldn’t conform her behavior to the law.

The fires were set over two weeks in 2006 in Irmo, a suburb of Columbia.
