DES MOINES, Iowa — Police have charged a man in the shooting death of another man last year near a Des Moines elementary school.

Des Moines police said in a news release Friday that detectives arrested 19-year-old Jahmar Saheim Mustin, of West Des Moines, charging him with first-degree murder and criminal gang participation in the May death of 23-year-old Choice Elliston.

Police say Elliston was shot outside Monroe Elementary on the northwest side of the city, causing the school to be locked down briefly.

Elliston was taken to a hospital, where he died a day after the shooting.
