False confessions often play a role in convicting the innocent. Marty Tankleff's is such a case. Here's a summary of Marty Tankleff's case from Fortress Innocence:
Marty Tankleff had just turned 17 years old when he was arrested for the murder of his parents in their Long Island home. After hours of aggressive interrogation by a detective with a questionable background, a dubious and unsigned "confession" lead to Marty's conviction. He was sentenced to 50 years to life in prison, with the possibility of parole in 2040. "Wrongful convictions are an epidemic in our justice system, and people need to become educated on the rampant corruption that is a threat to all of us," says Marty.
After more than 17 years in prison, Marty's conviction was vacated by the New York State Appellate Division in December of 2007. On July 22, 2008, a judge signed off on a motion by Attorney General Andrew Cuomo to dismiss all charges against Marty. Cuomo announced he would not retry Marty, citing insufficient evidence to prove his guilt. A State Supreme Court Justice dismissed all charges against Marty Tankleff in the murder of his parents, and a report is still pending from the NY State Commission of Investigation about Suffolk County law enforcement for its conduct in Marty's wrongful conviction.
