ASHDOWN, Ark. (AP) - A woman charged in the fatal shooting of a 17-year-old girl during a birthday party in southwest Arkansas has pleaded guilty in the case and has been sentenced to 47 years in prison.

Authorities say 41-year-old Traci Dierks was serving alcohol to minors at her residence near Foreman on Jan. 23, when a rifle she was carrying discharged, striking Caitlin Caskey in the chest.

The birthday party was for Dierks' 16-year-old daughter.

The Texarkana Gazette ( reports that Dierks changed her plea on Monday before a judge sentenced her to 30 years in prison for second-degree murder. Dierks also received prison time for multiple counts of aggravated assault and contributing to the delinquency of a minor.
