Cases in which all investigative leads appear to be exhausted are frustrating for both investigators and victims’ families. Cold cases can range from those only a few months old to others that go back for decades. Presenting profiles and actual case histories, Cold Case Research: Resources for Unidentified, Missing and Cold Homicide Cases illustrates how investigators can successfully apply resources that will enable them to reopen and solve cases gathering dust in the file room. Today’s investigators have found that, to solve cold cases, they need to be internet savvy and make the best use of the rapidly changing methodologies of the twenty-first century, but they also have to be time travelers and open the door to the past. This volume weaves together the nearly forgotten skill sets of traditional historical researchers with the latest online tools, including TLO, a premier investigative system; and NamUs, the revolutionary database for missing persons and unidentified remains. Along with practical applications, Cold Case Research gives investigators the tools they need to save time and money and to jump-start their cold cases, while keeping others from going cold in the future. Topics discussed include: Implementing cold case units People searches and working with databases Overlooked DNA in PKU cards The plight of the missing and unknown Applying historical and geographical context Online and off-line newspaper research Public and published records The use of volunteers Contact with co-victims Cold-case review teams and information-sharing resources Taking advantage of the media Using a thinking-outside-the-box approach, this volume helps fill major gaps in traditional cold case investigation training and techniques, enabling investigators to confidently reopen and crack the mystery of cases long thought unsolvable.

In 1954, two college students were hiking along a creek outside of Boulder, Colorado, when they stumbled upon the body of a murdered young woman. Who was this woman? What had happened to her? The initial investigation turned up nothing, and the girl was buried in a local cemetery with a gravestone that read, "Jane Doe, April 1954, Age About 20 Years." Decades later, historian Silvia Pettem formed a partnership with law enforcement and forensic experts and set in motion the events that led to Jane Doe's exhumation and eventual identification, as well as the identity of her probable killer. The 2023 paperback edition includes an epilogue with updated information on how the mystery finally was solved.
Because the investigation of cold cases is usually an arduous and time-consuming task, most law enforcement agencies in the United States are not able to dedicate the resources necessary to support the cold case investigation process. However, when those cases are fully pursued and prosecuted, they often result in convictions and lengthy prison terms.

It also provides techniques for developing investigative strategies to complement the evaluation process and resolve the crime.

COLD CASE CHRONICLES tells the stories of victims –– some missing, some murdered and some with changed identities. All are true, and each are mysterious in their own ways. The cases in this nonfiction narrative date from 1910 through the 1950s and include evolutions in forensics, as well as historical context in order to view the men, women and children through the lens of time. Included are recent theories on the cases of Judge Joseph Crater (missing from New York City in 1930) and film director William Desmond Taylor (shot in Hollywood in 1922). Other chapters help to unravel the mystique of individuals with changed identities. Included, too, is a case of aerial sabotage, the "Boy in the Box," and unusual disappearances of young women, along with child abductions and four missing adventurers –– Everett Ruess, Joseph Halpern, and Glen and Bessie Hyde. Readers are encouraged to draw their own conclusions, consider how detectives would handle these and other cases today, and learn how genetic genealogy brings new hope for the future.

Nearly 185,000 homicides since 1980 remain unsolved, yet with limited staff and resources, it is no surprise that law enforcement units place the bulk of their efforts on current cases where victims’ family members and the media demand answers. Cold Cases: An Evaluation Model with Follow-up Strategies for Investigators provides a comprehensive roadmap for digging those cold cases out of the file room and getting them resolved. Practical and concise, the book is an invaluable tool for police officers and detectives attempting to solve crimes that would otherwise be forgotten. Evaluating the Case Divided into three sections, the book begins with a historical perspective on how cases get to the point where it appears all investigative leads have been exhausted. It includes a chapter on understanding the process of homicide and those who kill — critical information for the homicide investigator. Next, the authors explain the evaluation model. They demonstrate the key elements of organization, thoroughness, and the value of the scientific method. This section validates theories of the crime, raises evidentiary issues and concerns, addresses the informational and behavioral aspects relative to the crime and the participants in the crime, and documents investigative strategies for future efforts on the case. Investigating and Solving the Crime The third section discusses the investigation that follows the evaluation. The book considers questions investigators must ask, including what should be looked at beyond the case file itself, and how the growth in technology since the date of the incident might provide new opportunities to uncover clues. This section also explores the choice of interview/interrogation techniques based on the behavioral aspects involved. Finally, the authors suggest how investigators can maximize their efforts and obtain not just an arrest, but a conviction. Useful appendices include sample standard operating procedures from three different agencies to use as a guide for setting up a cold case unit and a list of additional resources a department may look to for assistance. By following the cold cases evaluation model in this volume, those charged with resolving long-forgotten crimes can increase their chance of an accurate resolution, or at least be able to say that everything that can be done has been done.
