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. Silvia Pettem was quoted in a January 29, 2012 article on missing persons in the Colorado Springs Gazette.

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. Cold Cases: Evaluation Models with Follow-up Strategies for Investigators, Second Edition saves law enforcement time by providing detailed guidelines for determining if a cold case is solvable, and if so, how to organize, manage, and evaluate the investigation. It also provides techniques for developing investigative strategies to complement the evaluation process and resolve the crime. This second edition features a new revised model and methodology for investigating cold cases suitable for all police and public safety agencies—large or small, domestic or international. This new model is more expeditious and convenient for departments that have less manpower and experience in dealing with cold cases. It emphasizes the prioritization of cold cases based on the availability of physical evidence and the chances of deriving matches from said evidence and an identified person of interest. Additional topics covered in the second edition include: How cases go cold Strategies for creating a cold case unit Cold case investigations in a Dutch educational environment—a chapter written by members of the Dutch Police Academy New forensic science technologies, including DNA, CODIS, and AFIS Case studies demonstrating advances in suspectology Strategies for effective investigative interviewing Challenges posed by staged crime scenes in cold cases How to craft a cold case evaluation report The expert authors of this book maintain The Center for the Resolution of Unresolved Crimes and conduct training and consulting worldwide. Their practical book is designed to help law enforcement agencies resurrect long-forgotten cases, bringing closure to victims and holding accountable those who are responsible. This book is part of the Advances in Police Theory and Practice series

This book, now in its second edition, is the first and most exhaustive text covering the still growing popularity of cold case investigations which locate perpetrators and free the innocent.

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.

When loved-ones go missing, the lives of their family members are turned upside-down. As the days and months turn into years, some families are caged in by their grief, while others become proactive –– renewing police contacts, keeping up with the latest technologies, and educating themselves as they strive to become their long-term missing persons’ advocates. By inspiring hope, as well as providing answers and practical advice, The Long Term Missing: Hope and Help for Families assists families in navigating the uncharted territory they never chose to enter. Author Silvia Pettem also provides families with information to better understand how law-enforcement and related agencies work to solve missing persons cases. Along the way, she takes her readers behind the scenes, while emphasizing that every unidentified person is a missing person to someone else. With real cases, both solved and unsolved, the book also illustrates the resources available and the actions that family members, civilians, and law enforcement agencies can take to search for long-term missing persons, to identify previously unknown remains, and to bring the missing persons home. The Long Term Missing: Hope and Help for Families inspires hope and gives answers as it empowers family members of long term missing persons to be proactive and to become their missing persons’ advocates.
