William Marshall III, a 17-year-old high school student, is wanted for the first-degree murder of Angelo Little, who was also 17, at the Mall in Columbia. The shooting, which occurred on July 27, was targeted according to police, though a motive remains unclear. Marshall, who has not attended school this year, is believed to have fled the area, prompting police to release his identity publicly for safety reasons. Despite extensive search efforts, including reviewing surveillance footage and working with federal partners, authorities have been unable to locate him. A reward of $10,000 is being offered for information leading to his arrest, and police are appealing to the public for assistance. Anyone with information is urged to contact Howard County police.
