Statute of limitations extension due to obstructing evidence?

Before indictment, the statutes of limitation, and in extreme circumstances, the due process clauses protect the accused from unreasonable delays. That being said, if the accused had been charged and acquitted in a previous case and new evidence was unearthed that could have potentially changed the outcome of the trial due to "obstruction of evidence pertaining to state or federal cases, i.e.", or other extreme circumstances then yes, the statute of limitations can be extended.
