2008_06_tankleff.jpgAfter serving 17 years in prison for his parents' 1988 murders until charges were dropped in January, Martin Tankleff learned today that he won't be retried for their murders. Tankleff's had lawyers claimed that the then-17-year-old Tankleff was tricked into confessing and pointed to evidence that suggested Tankleff's father's business associate could have been been behind the killings. Today, Attorney General Cuomo's office said, "The issue in this case is not whether there is evidence ...but whether there is sufficient evidence," and doesn't think there's enough evidence to prosecute anyone else.
