Antonio Carl Boone, 20, known to friends and family as Rome, was found dead near Northern Shores Elementary School in the Burbage Grant neighborhood of Suffolk, Virginia, on March 5, 2013. He suffered a gunshot wound to the head; authorities ruled his death a homicide and the discovery prompted a precautionary lockdown of the school.

Police say 911 calls about gunshots and a body near Respass Beach Road brought officers to the scene just before noon. It is believed Boone was walking along that road when he was fatally shot. The killing was recorded as the city’s second homicide of the year.

The case has grown cold. No arrests have been announced and no suspects have been publicly identified. Anyone with information about Boone’s movements that day or who saw activity near Respass Beach Road or Northern Shores Elementary is asked to come forward.
