Shortlisted for The Brass Knuckles Award for Best Nonfiction Crime Book, Crime Writers of Canada Awards Get inside the mind of an elite cold case investigator and learn how to solve a murder. Despite advances in DNA evidence and forensic analysis, almost half of murder cases in Canada and the US remain unsolved. By 2016, the solved rate had dropped so significantly in the United States that it was the lowest in recorded history, with one in two killers never even identified, much less arrested and successfully prosecuted. And the statistics are just as bad in Canada. As a sought-after global expert and former detective, Arntfield has devoted his career to helping solve cold cases and serial murders, including the creation of the Western University Cold Case Society, which pairs students with police detectives to help solve crimes. In How to Solve a Cold Case, Arntfield outlines the history of cold case squads in Canada and the US, and lays out the steps to understanding and solving crime. Arntfield shows you what to look for, how to avoid common mistakes, recognize patterns and discover what others have missed. Weaving in case studies of cold crimes from across Canada and the US, as well as a chapter on how armchair detectives can get involved, How to Solve a Cold Case is a must-read for mystery fans and true crime buffs everywhere.

Solving a cold case is extremely difficult and many are left unresolved. In this book, retired NCIS Special Agent Joe Kennedy details the methodology he created to solve cold case murders. He offers an in-depth, behind-the-scenes look into why cases go cold, how they are investigated and what is needed to successfully resolve them. Author Kennedy shares his motivations and the lessons he has learned while solving these challenging cases. Also examined are cold cases where other detectives have successfully implemented Kennedy's methodology. Many books delve into the perspectives of criminals who commit murder, but this text takes a fascinating gumshoe journey into the mind of a cold case detective and his passionate search for the truth. Helping law enforcement solve cold cases brings justice and resolution for the victims and their families, and this book provides detectives and true crime enthusiasts the tools to investigate cold cases in their own communities.

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.

A campus podcast with chilling repercussions. Lucas Vega is obsessed with the death of Candace Swain, who left a sorority party one night and never came back. Her body was found after two weeks, but the case has grown cold. Three years later while interning at the medical examiner's, Lucas discovers new information, but the police are not interested. Lucas knows he has several credible pieces of the puzzle. He just isn't sure how they fit together. So he creates a podcast to revisit Candace's last hours. Then he encourages listeners to crowdsource what they remember and invites guest lecturer Regan Merritt, a former US marshal, to come on and share her expertise. New tips come in that convince Lucas and Regan they are onto something. Then shockingly one of the podcast callers turns up dead. Another hints at Candace's secret life, a much darker picture than Lucas imagined—and one that implicates other sorority sisters. Regan uses her own resources to bolster their theory and learns that Lucas is hiding his own secret. The pressure is on to solve the murder, but first Lucas must come clean about his real motives in pursuing this podcast—before the killer silences him forever.

Between 1985 and 2004 a staggering 8,894 unsolved homicides were committed in New York City. Here is the first ever inside look at the elite NYPD squad that cracks these “unsolvable” cases. In this fascinating, in-depth narrative, Stacy Horn uses her unprecedented access to the NYPD Cold Case Squad to immerse herself into four unsolved murder cases—cases going back as far as 1951—investigated by three indefatigable Cold Case detectives. Each detective uses his own contacts, informants, and resources and sifts through decades-old evidence, searching for new leads, looking for what others missed, and uncovering any possible connections. These Cold Case detectives are on a constant hunt for the needle in the haystack, and Stacy Horn puts you there every step of the way. From the grisly circumstances and desperate reconstructions of the crimes, through the endless legwork, the scientific advances that don’t always yield hoped-for answers, and the harrowing politics and tangled history of the storied NYPD, Horn depicts the drama of each case, and lays out the puzzle as seen through the eyes of the detectives. At once contemplative and energetic, The Restless Sleep is a completely addictive, fly-on-the-wall story of a subculture of crime solving, and of the people who must beat the odds to offer a final resolution for the unavenged.
