Raekwon Mangrum was 19 when he was killed in a sudden, multi-shot attack on a spring evening in April 2015. He was outside a home on North Monroe Street in Wilmington, Delaware, when he was shot multiple times and died of his injuries. An 18-year-old woman who was with him was also shot in the leg and survived.

Wilmington Police pursued the suspects’ getaway car in a high-speed chase that went through city streets onto Interstate 95 and into Pennsylvania, where state and local officers helped end the pursuit. Two occupants, Atiba Mayfield and Michael Broomer, were arrested. Investigators identified Mayfield, then 22, as the shooter and Broomer, then 21, as the driver.

A New Castle County Superior Court jury later convicted Mayfield of Murder in the First Degree and related firearms and conspiracy counts; he faced a life sentence. Broomer was convicted of Murder in the Second Degree and related charges and faced a sentence of 21 years to life. Did anyone in Wilmington remember Mangrum or witness the shooting or the getaway that night?
