On November 16, 2018, the body of 23-year-old Derek Whalen was found in a vacant apartment on Chesapeake Drive in Florissant, Missouri. He had been fatally shot. Friends and family remembered Derek as lovable and fun-loving, someone who enjoyed rapping and dancing and worked at a local Imo’s Pizza.

Investigators tied the shooting to an argument that began after a car accident. Witnesses identified Deion Whalen as the person who fired the fatal shots. Deion was arrested and originally charged with second-degree murder and armed criminal action. During the case there was an incident in which the courthouse building was struck by gunfire. A jury ultimately convicted Deion of first-degree involuntary manslaughter and armed criminal action and returned consecutive ten-year prison terms; the Missouri Court of Appeals later upheld the verdict and sentence after appeals raised issues including jury selection and prosecutor statements.

Does anyone have information about Derek’s final movements or the crash that preceded the confrontation?
