Police in the Dominican Republic say they have killed one of two men suspected in the slaying of an elderly German tourist during a robbery.

The tourist was walking with his wife along the seawall Thursday evening in Puerto Plata when the couple was accosted by two assailants. Police Chief Nelson Peguero said 76-year-old Ernst Gunter Haun apparently struggled with the men when they tried to take a necklace and was fatally shot.

Peguero said officers identified the assailants from surveillance camera footage and located them several hours later. He said a 22-year-old suspect was killed in a shootout. The other remained at large.

Tourism Minister Francisco Javier Garcia called for a special commission to investigate the attack in Puerto Plata, which is crowded with tourists for the high season.
