COLUMBIA — South Carolina’s top federal prosecutor is announcing winners of a contest for school children to design a logo for upcoming gun violence prevention publications.

U.S. Attorney Bill Nettles says students from schools in Campobello, Cordova, Columbia, and Darlington have won grade-level competitions in his office’s 8th Annual Project Sentry Logo Contest. He is to announce the winners on Friday.

The students come from Edisto Primary School in Cordova, Harbison West Elementary School in Columbia, Campobello Gramling School and the Darlington County Institute of Technology.

The statewide contest gives students an opportunity to illustrate how they prevent gun violence in school by designing a logo for use on upcoming Project Sentry publications.

Winners receive a $100 savings bond. The overall winner is featured in Project Sentry publications.
