Cold case murders are those defined that for one reason or another have not been solved. Cold case crimes are among the most difficult to solve for many reasons and the longer the case goes unsolved, the less likely they are to ever come to closure. Despite increasing advances in scientific and forensic technology, it's not always the physical evidence that determines the resolution of a homicide. In most trials today, it's also vitally important to tie the suspect to that physical evidence. Never Solved: The True Stories of America's Most Notorious Unsolved Murders is the 5th of John Summit's True Crime books and profiles seven stories of the most notorious true crime mysteries in American history. These cases will leave you flabbergasted at the bungled police stories, leave you wondering how likely suspects were never prosecuted and leave you sympathizing with the families of the victims who never saw closure.

Are criminals who have been convicted of murder really being released back into society to live among us? WARNING: The cases profiled in this thought provoking book will both disturb and anger you. Recidivism, as defined in psychiatry journals, is the chronic tendency to repeat anti-social or criminal behavior patterns. Prison systems, in part, are intended to rehabilitate the criminal so these same behavior patterns will not be repeated. However, when an individual commits the most serious of crimes - murder - and then they're convicted of that crime, most receive life in prison or the death penalty. So, how is it that the criminal justice system is failing so horribly and releasing them after committing such violence in society? Released to Kill Again is the 4th volume in the True Crime Series by John Summit. In this audiobook, he reveals the shocking true crime and murder stories of 7 convicted criminals who not only killed once, but were paroled...only to kill again.
