Ann Campbell pleaded guilty Thursday to the murder of one of her sons and the attempted murder of another.

Campbell entered the plea at the Chilton County Courthouse with Judge John Bush presiding.

Bush told Campbell that each charge carries a sentence of 20 years to life in prison.

Sentencing is set for Jan. 3, 2013, at the courthouse.

Campbell was arrested and charged after a June 2011 incident at her home in the Enterprise community left 11-year-old Michael Campbell dead and Bailey Mays, who was 15 at the time, injured from a gunshot.
