An NBC Dateline producer's account of his two-decade-journey through the criminal justice system to free six innocent men falsely imprisoned for murder.

It wasn’t the September 11 attacks or the murders he’d investigated for the NYPD that haunted him, the detective told journalist Dan Slepian, but a 1990 case where two men were sentenced to twenty-five years to life in prison for a murder they didn’t commit. When Slepian, a veteran producer for NBC’s Dateline, asked how he knew they weren’t guilty, the cop replied, “Because I know who the real killers are.”

Slepian couldn’t shake what the detective had told him—and what it said about the criminal justice system. It began a two-decade-long personal and professional odyssey in which Slepian used his investigative skills to prove the innocence of not just those two men, but of four others also falsely convicted of murder by New York courts.



The Sing Sing Files: One Journalist, Six Innocent Men, and a Twenty-Year Fight for Justice is Slepian’s cinematic account of challenging a system fiercely resistant to rectifying or even acknowledging its mistakes and their consequences. The reader follows Slepian on prison visits, street reporting, and during his interactions with prosecutors, defense attorneys, witnesses, and police for the Dateline stories that eventually led to freedom for the imprisoned men.

At the book’s center is the friendship that developed between Slepian and Jon-Adrian “JJ”

Velazquez, who, from his cell at Sing Sing, directed Slepian to other innocent men until he, too, was finally released in 2021 after serving decades in prison.

Like Bryan Stevenson’s Just Mercy, The Sing Sing Files is a powerful account of addressing wrongful imprisonment but in the nation’s largest city, not the rural South. Slepian’s extraordinary book, at once infuriating and full of hope, shines a light on an injustice whose impact the nation has only begun to confront.

Praise for Dan Slepian

"Compelling and emotionally wrenching....starkly illuminating the unimaginable suffering of the wrongly imprisoned and their families."

Book Reviews

"You couldn’t blame anyone wrongfully incarcerated for trying to get ahold of Slepian, whose dogged reporting for NBC’s Dateline has helped free several innocent men and is the subject of his new book, The Sing Sing Files. It’s a riveting read—and an infuriating one."

Vanity Fair

"Dateline producer Slepian debuts with a riveting account of his crusade to free six wrongfully convicted men from New York State’s Sing Sing prison... Slepian tells his subjects' stories with rigor and compassion, and persuasively argues that America’s justice system is “designed to easily imprison the innocent” in the name of closing cases quickly. This is difficult to shake."

Publishers Weekly

“A gripping, highly effective true-crime synthesis… an excellent addition to the body of work documenting a pervasive societal injustice.”

Kirkus
STARRED REVIEW

“Dan Slepian’s debut book The Sing Sing Files sounds the alarm on a criminal legal system that too often victimizes instead of protects. The beautifully told story of Slepian’s twenty year personal journey and proximate relationships with 6 wrongfully convicted innocent men, should be a civics textbook used to raise awareness, promote action and demand true and accurate accountability.”

“In my criminal law class, we were taught that one of the underlying principles of our criminal justice system is that we would rather let a guilty person go free before convicting an innocent person. Thirty years later, as an Assistant Attorney General at the U.S. Department of Justice, I learned the reality of our criminal justice system at the joint launch of recommendations by the U.S. Office for Victims of Crime, the Innocence Project and the International Association of Chiefs of Police to reduce wrongful convictions. Your book illustrates on a deeply personal level what happens to real people, to their families and trust in our core systems when people are sent to prison, often for decades, for crimes they didn't commit. I hope this book, which I stayed up all night reading, captures the hearts and minds of all of us. We all play a role in allowing these miscarriages of justice to continue unless we collectively commit to seeing the flaws in our justice system and commit to rectifying them."
