It took nearly 30 years for that conviction to be overturned -- and it might never have happened without help from the same office that prosecuted him. Reporter Sabine Jansen tells the story of the Brooklyn Conviction Review Unit, the DAs who re-investigate their colleagues’ work, and the collaboration that finally set an innocent man free.
