The Supreme Court has reinstated the murder conviction of Pedro Hernandez for the 1979 kidnapping and death of Etan Patz.This 6-3 ruling effectively overturns a lower federal court decision that had previously vacated the conviction.The high court determined that federal judges should not interfere with state criminal trial evidence and jury findings.Prosecutors had warned that a third trial for the suspect would be impossible due to the many years that have passed.
