An all-new season of ‘Dateline: Missing in America’

In December of 2002, NBC News producer Dan Slepian got a letter from a New York state prison. It was from a man serving 25 years to life for murder. And it ended with a desperate plea: look into my case.  

Jon-Adrian “JJ” Velazquez had been convicted of killing a retired New York City police officer, but he insisted he didn’t do it. Dan was skeptical. Prosecutors said five eyewitnesses had sworn JJ was the killer. Could five people be wrong?

So Dan began to dig. What he discovered went far beyond just JJ’s case. And 20 years later, it’s still unfolding.

Letters from Sing Sing tells the story of a man convicted of murder, a journalist, and the letter that changed both of their lives. New episodes drop every Monday through March 27, 2023.
