Vincent James Landano was released in 1990 after serving 13 years in prison for the murder of John Snow, a New Jersey police officer. The police had withheld potentially exculpatory evidence, resulting in a new trial, an acquittal and a civil suit against the state. Ask Landano who committed the murder and he’ll tell you: The Breed, a Long Island motorcycle gang. Funny, ask us who committed an unsolved murder, from JFK to Jack the Ripper, and our answer stays the same — We don’t know.
