Christopher Sullen, 36, was shot dead on September 23, 2016, inside a residence near East 144th Street and Kinsman Road in Cleveland. Family remembered him as smart, polished, and caring; he is survived by companion Roshawnda Wynn, parents Bobby Sullen and Darlene Clinkscales, and his children Christopher and Christian.

Police and state and federal investigators determined the shooting was part of a multiple-victim attack. Evidence including DNA and gun tool mark analysis linked 35-year-old Terrell Silver to this and other killings; Silver was convicted on counts including aggravated murder, murder, felonious assault and aggravated burglary and received five consecutive life terms without parole.

The case underscores the loss felt by the family and the role of forensic evidence in securing convictions. If anyone knew Christopher, his movements that night, or has additional information about the residence near East 144th and Kinsman, please come forward.
