On the evening of Monday, April 18, 2016, Richard Alan Cushingberry, 30, was shot at his home in the 5000 block of Fairway Drive in Kansas City, Missouri. He answered a knock shortly after 8:00 p.m. and was met with gunfire; assailants shot him four times in the chest. He was taken to a hospital and died early the next morning, Tuesday, April 19.

Family described Cushingberry as a devoted father and a big kid at heart who enjoyed video games and cooking. He left three young children, then ages 7, 9, and 10, and his mother and sister held a vigil on his lawn. Detectives with the Kansas City Police Department investigated but had not identified a suspect or made arrests in the months after the shooting. He had been recovering from a back injury and spending time with his children; family members said they did not know who would want to harm him. Reports note he had earlier been a witness in a federal case about a firearm stolen from his possession years before, but authorities did not publicly connect that matter to his killing.

Who knew Richard or was in the neighborhood that night and can help explain who knocked on his door?
