Statistics, 50 percent of 2024 homicide victimizations were cleared by arrest, while 45 percent were not cleared. These figures should be interpreted carefully. A clearance rate is a measure of law-enforcement case outcomes during a particular reporting framework; it is not a count of all cold cases accumulated over American history. Cases can be solved later as new evidence emerges, witnesses come forward, forensic methods improve, or investigators reopen old files. Nevertheless, the 2024 figures demonstrate why unresolved killings remain a substantial concern even in a year when the overall homicide rate declined.
Solving a homicide can depend on a complicated combination of evidence and cooperation.
Every unresolved homicide and missing-person case represents more than an entry in a database. Behind each case is a person, a family searching for answers, and a community living with uncertainty. Although advances in forensic science, digital records, DNA analysis, and information sharing have given investigators tools that earlier generations could scarcely imagine, thousands of serious cases remain unresolved across the United States. Recent federal statistics show both the scale of the problem and the complexity of measuring it. Homicides and missing-person investigations are tracked through different systems, and an uncleared homicide is not automatically a permanently unsolved case, just as a missing-person report does not necessarily mean that a person remains missing for years. Understanding those distinctions is essential to understanding the national challenge.
The Scope of Unsolved Homicides
The Bureau of Justice Statistics estimated that 17,420 people were victims of homicide in the United States in 2024, a rate of 5.1 per 100,000 residents. That represented an 18 percent decline from the 2023 rate and a 23 percent decline from the 2022 rate. The decrease is important because it shows that homicide levels can move significantly over relatively short periods. Yet a falling homicide rate does not eliminate the burden created when killings remain unresolved.
Clearance statistics offer one way to understand that burden. According to the Bureau of Justice Investigators may need reliable eyewitness testimony, surveillance video, digital records, firearm evidence, DNA, fingerprints, phone data, or information supplied by people who knew the victim. Some cases begin with abundant evidence. Others may involve few witnesses, incomplete records, deteriorated physical evidence, or
circumstances that are not immediately known. Time can make these difficulties worse: memories fade, witnesses move or die, and physical evidence can deteriorate. At the same time, time can sometimes help an investigation when new technology allows old evidence to be examined in ways that were impossible when the crime occurred.
Why Cold Cases Matter
An unresolved homicide can have consequences far beyond the original crime scene. Families may spend years without knowing who was responsible or whether an arrest will ever occur. That uncertainty can complicate grief because there may be no clear conclusion to the criminal investigation. Communities can also lose confidence when residents believe serious crimes repeatedly go unanswered. That loss of trust can itself make investigations harder if people become reluctant to share information with law enforcement.
Cold-case work therefore requires persistence as well as technology. A case that was difficult to investigate twenty or thirty years ago may contain evidence that has new value today. DNA analysis has become increasingly powerful, digital databases can connect information held in different jurisdictions, and forensic specialists can revisit unidentified remains or previously inconclusive evidence. Dedicated cold-case units can also give older investigations something they often need most: fresh attention. A new investigator may identify a neglected lead, locate a witness who is now willing to speak, or recognize a connection that was not apparent in the original investigation.
Resources, however, are finite. Police departments and sheriff’s offices must investigate new crimes while preserving thousands of older files. Evidence has to be stored correctly, records must remain accessible, and forensic testing can require specialized personnel and laboratory capacity. These practical demands mean that improving homicide clearance cannot depend on one technological breakthrough alone. It requires sustained investment in investigators, laboratories, evidence management, information sharing, and relationships with the public.
The Scale of Missing-Person Reports
Missing-person statistics tell a different but equally important story. The FBI’s National Crime Information Center reported that 533,936 missing-person records were entered during 2024. During that same year, 537,446 records were purged. The FBI explains that records can be removed because law enforcement located the person, the person returned home, or the entering agency determined that a record was invalid. Consequently, the number of reports entered during a year should not be interpreted as the number of people who remain missing indefinitely.
At the end of December 31, 2024, NCIC contained 93,447 active missing-person records. Of those records, 25,493 involved juveniles younger than 18, representing 27 percent of the active total. When juveniles are defined as people younger than 21, the figure rises to 34,256 records, or 37 percent. These numbers demonstrate why missing-person investigations involve both a large volume of reports and very different circumstances. A person may be listed as endangered, involuntarily missing, a juvenile, a catastrophe victim, a person with a disability, or under another qualifying category.
A missing-person case also differs fundamentally from a homicide investigation because investigators may initially know very little about what occurred. A disappearance can arise from many circumstances, and authorities cannot assume at the outset that a crime occurred. The immediate priorities are often to determine the person’s whereabouts, assess risk, reconstruct a timeline, contact friends and relatives, examine available records, and identify any circumstances suggesting danger. Speed can be especially important when evidence indicates that a missing person is endangered.
Public attention can help, but accurate information is critical. Photographs, physical descriptions, vehicle information, known locations, and verified timelines may help people recognize a missing person or provide a useful lead. At the same time, rumors and unsupported accusations can misdirect attention and cause additional harm. Effective public participation depends on sharing verified information through appropriate law- enforcement and missing-person channels rather than attempting to conduct an independent investigation online.
Connecting Missing People With Unidentified Persons
One of the most difficult problems occurs when investigators have a missing-person report in one jurisdiction and unidentified human remains in another. The connection may not be obvious, particularly when years have passed or jurisdictions use separate records. The National Missing and Unidentified Persons System, known as NamUs, was created to help address this problem. Operated by the National Institute of Justice, NamUs provides a centralized federal program and database supporting missing, unidentified, and unclaimed-person cases.
The National Institute of Justice reported in its fiscal year 2024 annual report that 61,492 missing, unidentified, and unclaimed NamUs cases had been resolved since the program began. More than 11,300 identifications were reported as having been made through techniques including DNA comparisons, forensic genetic genealogy, dental analysis, fingerprints, anthropology, and radiograph comparisons. The report also illustrates that the public can sometimes contribute directly: during fiscal year 2024, more than 50 cases were
resolved through family members recognizing photographs of loved ones or images of personal effects displayed through NamUs.
Those outcomes highlight the importance of combining databases with forensic science. A name in a missing-person system and an unidentified decedent record may contain different pieces of the same story. DNA profiles, dental records, fingerprints, medical information, tattoos, personal belongings, and other identifiers can help investigators establish a match. Improvements in forensic genetic genealogy have created another avenue for some difficult cases, although such work requires careful investigative practices and appropriate legal and privacy safeguards.
Interagency cooperation is equally important. People do not disappear according to jurisdictional boundaries. A person reported missing in one state may travel elsewhere, while unidentified remains may be recovered hundreds of miles from the location where the person was last seen. Effective investigation therefore depends on local, state, tribal, and federal agencies being able to share accurate information and compare cases across geographic boundaries.
The Human Cost
Statistics are useful for describing the national scale of unresolved cases, but they can also obscure the people represented by them. A family dealing with an unresolved homicide may repeatedly revisit the circumstances surrounding a loved one’s death. A family of a missing person may live with a different kind of uncertainty, not knowing whether the person is safe or whether there will ever be an explanation. Anniversaries, birthdays, and new investigative developments can renew that uncertainty long after public attention has moved elsewhere.
This human dimension is one reason communication between investigators and families matters. Even when a case has no major new development, clear communication can help families understand whether an investigation remains active, what information can legally be disclosed, and where they can submit new evidence. Families may also hold photographs, dental information, identifying details, or other records that become important when investigators compare missing-person cases with unidentified remains.
Communities also have an important role. Trust between residents and investigators can affect whether witnesses report what they know. Community organizations, victim advocates, and responsible media coverage can keep attention on unresolved cases without sensationalizing victims or compromising investigations. Public awareness is most useful when it directs credible information toward investigators and respects the fact that incomplete evidence should not be treated as proof of guilt.
What Can Improve Case Resolution
Reducing the number of unresolved cases requires several strategies working together. First, agencies need reliable systems for preserving physical evidence and case records over long periods. A future scientific technique has little value if the underlying evidence was lost, contaminated, or poorly documented. Second, forensic laboratories need sufficient capacity to process evidence promptly while also reviewing older cases. Third, agencies benefit from investigators who specialize in cold cases and who have time to reexamine files systematically rather than only when a new tip arrives.
Fourth, databases must be accurate and interoperable. NCIC and NamUs serve different purposes, but both demonstrate the value of structured information that can be searched and compared. Consistent reporting, complete case records, and cross-jurisdictional cooperation increase the chance that seemingly unrelated information can be connected. Fifth, investigators need strong partnerships with families and communities. Technology may generate a lead, but witnesses, relatives, and people familiar with a victim’s life can supply context that databases cannot.
Finally, the public needs realistic expectations about what statistics mean. More than half a million missing-person records entered in one year does not mean that half a million people remained missing at year’s end. Likewise, a homicide that was not cleared during a reporting period should not automatically be described as permanently unsolved. Precise language respects victims and produces a more accurate picture of the problem.
A Continuing National Challenge
The United States has made significant advances in investigating homicide and missing- person cases, but federal data show that unresolved cases remain a serious national challenge. In 2024, the nation recorded an estimated 17,420 homicide victimizations, and Bureau of Justice Statistics data indicated that 45 percent were not cleared. Meanwhile, the FBI reported 93,447 active missing-person records at the end of the year, even as hundreds of thousands of missing-person records were entered and purged during the year. These two sets of statistics describe different systems, but together they demonstrate the enormous investigative workload facing agencies and communities.
There is also reason for measured optimism. Homicide victimization fell substantially in 2024 compared with the two previous years, and programs such as NamUs show that long- standing cases can be resolved through DNA, fingerprints, dental records, forensic genealogy, family recognition, and other techniques. A case that cannot be solved today is not necessarily beyond resolution tomorrow.
The most effective response is therefore neither resignation nor sensationalism. It is sustained investigative work: preserving evidence, improving forensic capacity, sharing information across jurisdictions, maintaining accurate databases, supporting families, and building enough community trust for witnesses to come forward. Every case resolved restores a name, an answer, or a measure of accountability. For families who have waited months, years, or decades, that work can make the difference between permanent uncertainty and finally knowing what happened.
