A reward has now reached $50,000 for information that leads to the arrest and indictment of the person or people responsible for killing a Concord, New Hampshire couple. Stephen Reid, 67, and Djeswende Reid, 66, left their apartment complex on April 18 and went for a walk toward some trails. Family and friends did not see or hear from them after that, authorities said. Their bodies were discovered the night of April 21 in the area of Broken Ground Trails. They died of multiple gunshot wounds. Investigators are still seeking to identify a person of interest depicted in a sketch released on May 17. That person is described as a white male in his late 20s or early 30s, approximately 5’10” tall, medium build, with short brown hair, and clean-shaven. He was seen wearing a dark blue jacket, possibly with a hood, khaki-colored pants, and carrying a black backpack. Information can be submitted anonymously by contacting the Concord Regional Crimeline at (603) 226-3100.
