The FBI and other national databases track related, broader data, but they do not typically categorize the total number of "cold cases" specifically for youth separately from all other cold case data. Here is a breakdown of the relevant data and context: 1. Broad Cold Case Statistics The FBI's Uniform Crime Report (UCR) data, often analyzed by groups like The Murder Accountability Project, indicates a significant number of unsolved homicides overall.  • Nearly 340,000 cases of homicide and non-negligent manslaughter went unsolved from 1965 to 2021 across the United States. A "cold case" is generally a criminal investigation that has not been fully resolved and is not the subject of a current, active investigation, often because all viable leads have been exhausted.  • A percentage of these unsolved homicides involve juvenile victims, but the total number of youth victims within this cold case count isn't readily broken out. 2. Missing Youth Data The Federal Bureau of Investigation's National Crime Information Center (NCIC) compiles data on missing persons, which includes youth, but this number represents active missing person records and not specifically "cold cases" (which generally apply to unsolved crimes like homicides or sexual assaults): • In 2024, 349,557 reports of missing persons involving youth were entered into NCIC.  • Youth accounted for 27 percent of the active missing persons records remaining as of December 31, 2024. 3. FBI's Role in Youth Cases The FBI actively investigates violent crimes against children (VCAC) and child abductions, which can sometimes become cold cases:  • The FBI has jurisdiction to immediately investigate any reported mysterious disappearance or kidnapping involving a child of "tender age" (usually 12 or younger) under the Lindbergh Law.  • The Child Abduction Rapid Deployment (CARD) teams are deployed soon after an abduction has been reported, demonstrating the FBI's proactive involvement in these time-sensitive cases. While many abductions are resolved quickly, those that remain unsolved would fall into the cold case category. In summary, while the FBI is heavily involved in youth-related criminal investigations, a definitive, current number of youth cold cases across all federal and state jurisdictions is not a standard, published statistic.
