Alonso Martinez-Coello was an 18-year-old resident of Fort Worth, Texas, who was shot and killed during a suspected robbery on June 29, 2008. Fort Worth police found him late that Sunday evening with a gunshot wound and he was pronounced dead at the scene. Authorities described the shooting as the result of an attempted robbery and the case was assigned to the homicide unit. No arrests had been made by the time of reporting.
