The Sing Sing Files

The Sing Sing Files is Dan Slepian’s cinematic account of challenging the broken criminal justice system.

The book follows Slepian’s years of prison visits, court hearings, and street reporting that led to a series of powerful Dateline episodes and eventually to the freedom of six innocent men.

At the heart of the story is Slepian’s deep and lasting friendship with Jon-Adrian “JJ” Velazquez, who aided Slepian in his investigations from his cell in Sing Sing until his own release in 2021.

The book is a powerful argument for reckoning and accountability, highlighting the flaws in the justice system and the impact of wrongful convictions on individuals and society.
