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.

From the detective who helped catch the Golden State Killer, a memoir about investigating America's toughest cold cases, and the rewards - and toll - of a life spent solving crime.For a decade, from 1973, The Golden State Killer stalked and murdered Californians in the dead of night, leaving entire communities afraid to turn off the lights. Then he vanished, and the case remained unsolved.In 1994, when cold-case investigator Paul Holes came across the old file, he swore he would unmask GSK and finally give these families closure. Twenty-four years later, Holes fulfilled that promise, identifying 73-year-old Joseph J. DeAngelo. Headlines blasted around the world: one of America's most prolific serial killers had been caught.That case launched Paul's career into the stratosphere, turning him into an icon in the true-crime world. But while many know the story of the capture of GSK, until now, no one has truly known the man behind it all.In UNMASKED, Paul takes us through his memories of a storied career and provides an insider account of some of the most notorious cases in contemporary American history, including Laci Peterson's murder and Jaycee Dugard's kidnapping. But this is also a revelatory profile of a complex man and what makes him tick: the drive to find closure for victims and their loved ones; the inability to walk away from a challenge - even at the expense of his own happiness. This is a story about the gritty truth of crime solving when there are no 'case closed' headlines. It is the story of a man and his commitment to his cases, and to the people who might have otherwise been forgotten.

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.

These murder, suicide, and accident victims, separated from their names, are being adopted by the bizarre online world of amateur sleuths. It’s DIY CSI. The web sleuths pore over facial reconstructions (a sort of Facebook for the dead) and other online clues as they vie to solve cold cases and tally up personal scorecards of dead bodies. The Skeleton Crew delves into the macabre underside of the Internet, the fleeting nature of identity, and how even the most ordinary citizen with a laptop and a knack for puzzles can reinvent herself as a web sleuth.
