    THE LAS VEGAS MASSACRE CONNECTIONS—Mark Gray

    On October 1, 2017, Mary Jo von Tillow’s world changed forever. Her husband, Kurt, was killed in the Route 91 Harvest Festival mass shooting in Las Vegas, the deadliest in U.S. history. In just eleven minutes, her life—and the lives of thousands of others—were shattered. But what followed was more than grief. Out of devastation came unexpected bonds with other survivors, advocates, and families who knew the same kind of loss. From a 9/11 firefighter who turned his pain into kindness, to a victims’ rights attorney who changed national law, to fellow widows and survivors who refused to give up, Mary Jo discovered what it means to carry tragedy together. The Las Vegas Massacre Connections is both a deeply personal account and a collective portrait of resilience. Through Mark Gray’s in-depth reporting and Mary Jo’s courage to share her story, this book captures the enduring impact of Route 91 and the human strength that rises after unimaginable loss.

    Every Killer Leaves A Trace - Dennis Carson

    They blended in. They raised families, held steady jobs, and hid in plain sight. But behind the mask of normalcy, they were monsters—responsible for decades of terror, pain, and death. Every Killer Leaves A Trace is a chilling narrative nonfiction thriller that exposes moments that led to the shocking unmasking and ultimate capture of twenty-six of America’s most elusive killers. From accidental slips to cutting-edge forensic breakthroughs, each chapter reveals how justice caught up with murderers who thought they’d never be found.

These are not just stories of murder. They are blueprints of how justice, though often delayed, is never truly denied.

    25 FROZEN, 1 THAWED—Bob Cyphers

    25 Frozen, 1 Thawed: Murder and Mayhem in the Midwest takes readers deep into the heart of unsolved mysteries and chilling crimes that have haunted communities across the Midwest. From small towns shattered by sudden disappearances to cities rocked by violent acts, each chapter brings a different story—twenty-five cases left frozen in time, still waiting for justice. The book explores murders that stunned neighborhoods, kidnappings that tore families apart, and mysteries that investigators chased for years. In these pages, the quiet streets of Missouri, Illinois, and beyond become the backdrop for secrets, heartbreak, and unanswered questions. But not every case remains locked in ice. One story breaks free—the “thawed” case—where persistence and detail uncovered the truth and shows that even the coldest mysteries can sometimes find resolution. With a journalist’s eye for fact and a storyteller’s gift for detail, Cyphers presents the lives lost, the families still searching for answers, and the investigators who refused to give up. Rather than sensationalizing tragedy, the book restores humanity to the victims while revealing the lasting impact of crime on entire communities. 25 Frozen, 1 Thawed is a testament to memory, resilience, and the hope that justice may yet be found—even decades later. 25 FROZEN, 1 THAWED: Murder and Mayhem in the Midwest—Bob Cyphers

    GREG SCARPA, LEGENDARY EVIL—Jonathan Dyer

    Goodfellow, capo, killer, thief. A man so diabolically evil that he ordered his eldest son to murder his closest associate, and his youngest son to murder his best friend. When Greg Scarpa was in his early twenties he became a goodfellow in the Profaci family by swearing a blood oath to the Mafia, at the time the country’s largest organized-crime syndicate. And for 25 years he betrayed that oath and the men closest to him by acting as a paid informant for the FBI. He fed America’s premier law enforcement agency a steady stream of self-serving information accusing the men who trusted him with their lives of every crime he was himself committing. During those 25 years of treachery, Scarpa was a one-man crime wave who spent only 30 days behind bars thanks to his status as the FBI’s ultimate Mafia insider. His standing as a prized informant freed him to engage in mayhem and murder knowing he had a virtual license to kill with reckless abandon. Greg Scarpa, Legendary Evil is a deep dive that provides fresh insight into Scarpa’s malignant personality. Dyer peels back the layers of myth and misdirection to paint as complete and accurate a picture as possible of a man who murdered his enemies and betrayed his friends, of a bigamist who loved only money, of a feared and reviled man whose destructive appetites knew no bounds. GREG SCARPA, LEGENDARY EVIL: The Many Faces of a Mafia Killer—Jonathan Dyer

    THE MURDER OF DEBBIE GAMA—Justin Dombrowski

    The murder that still haunts a Pennsylvania city. On the morning of August 8, 1975, sixteen-year-old Debbie Gama disappeared after leaving her home in Erie, only to be found raped and strangled days later in a creek nearly thirty miles from her home. What followed was an investigation that lacked suspects or even evidence pointing to a viable suspect. That is, until a private investigator named Dan Barber uncovered evidence leading directly to her killer: her English teacher, Raymond Payne. After Payne’s arrest, Debbie’s mother, Betty Ferguson, embarked on her own quest for justice, which unexpectedly led her on an incredible journey of forgiveness. Utilizing newspaper articles, court documents and investigative files never before revealed, Justin Dombrowski presents a gripping narrative of one investigator’s pursuit of justice and a mother’s search for the truth.

    31 MURDERS-—Alvin A.J. Esau

    Many decades before Ted Bundy roamed the country there was serial killer Earle Nelson. During the 1920s, this geographically mobile killer went from city to city. His modus operandi involved getting into a house by pretending to be a person looking for a room to rent or inspecting a house that was for sale, and then strangling the landlady, often followed by having sex with the dead body. Robbery was frequently a secondary motive. After Nelson was captured in Canada in 1927, it was commonly reported that he had killed 21 women and a baby during the 1926-27 period. But were these the only cases linked to him? The author examines an additional nine unsolved murders of landladies, two of which have never been dealt with in previous literature. Based on decades of archival research, the author examines all 31 murders, relying on primary sources when available and a wide variety of secondary sources. For each murder, the book provides biographical sketches of the victim, outlines the police investigation and the various suspects, and covers any subsequent attempts to link Nelson to the crime by identification evidence of witnesses or by fingerprints. 31 MURDERS: Following the Trail of Serial Sex Killer Earle Nelson-Alvin A.J.

And it's ultimately a story of how revolutionary one voice can be. EXPERT WITNESS: The Weight of our Testimony when Justice Hangs in the Balance—Ann Burgess
