Sing Sing star Jon-Adrian JJ Velazquez spent more than two decades fighting for justice after being convicted of a murder he maintained he did not commit. The actor, who appears in the acclaimed A24 drama opposite Colman Domingo, served nearly 24 years behind bars before his unwavering determination to clear his name finally paid off in 2021. After prosecutors discovered new DNA evidence that they claimed cleared the actor, his controversial case culminated in an emotional conclusion in a Manhattan courthouse earlier this week.
