Newspaper accounts, on which NSSC bases this report, frequently do not list names and ages of those who are charged with the deaths of others. Such omissions were in some cases because the person charged was a minor. In some instances, persons were killed in drive-by school shootings, gang encounters or during melees in which the killer was not identified, and the killers were either never apprehended or were caught days or months after the crime was first reported. As a result, more is known about victims than about perpetrators and therefore information in this report relates more to victims than to perpetrators.
