Authorities identified 18-year-old Keymondreas Key as the person who allegedly shot Hayes; the shooting reportedly arose from a dispute involving Key’s girlfriend. Key was located, arrested and charged with criminal homicide. He was later indicted on first-degree murder and subsequently pleaded guilty to second-degree murder, receiving a 20-year prison sentence.
