As New York City averted a lawsuit from David Ranta, who spent 23 years in prison for a now-vacated murder conviction, the Brooklyn District Attorney’s Office announced the appointment of an outside advisory panel to help review other questionable convictions in the wake of the Ranta case.

On Thursday, City Comptroller Scott Stringer announced a $6.4 million settlement with Ranta, who had submitted a $150 million notice of claim against the city but had not yet filed a full-fledged suit.
