From what I read elsewhere, it involves the prosecutors not sharing evidence with the defense team.

> Prosecutors failed to share with Franco's defense team five cellphone data reports connected to people arrested for drug sales based on Franco's alleged lies.

> "New Yorkers must know that law enforcement, including prosecutors, are acting with the utmost integrity. We hold ourselves accountable to that standard," Manhattan DA spokesman Doug Cohen said. "After disclosing evidence that violated our discovery requirements, the People today consented to the Defense motion to dismiss the case against Joseph Franco. The presiding Judge dismissed and sealed the case."

> Cohen went on to say the assistant DA handling the prosecution was removed from her post as deputy unit chief and that the General Counsel's Office will conduct an investigation.

> "The Post-Conviction Justice Unit will continue its ongoing review of cases affected by former Detective Franco's misconduct, which has thus far resulted in the vacatur of more than 100 Manhattan convictions," Cohen said. — CBS News
