The alteration, destruction, concealment, fabrication, or removal of physical evidence with intent to impair its availability, integrity or authenticity in an official proceeding or investigation, a distinct statutory offense in many jurisdictions alongside the related but separate offenses of witness tampering and jury tampering, which target interference with a person rather than with physical evidence itself. Documented conduct constituting evidence tampering includes destroying a document under investigation, planting evidence to falsely implicate another person, or altering a digital record, and the offense is frequently charged alongside a broader obstruction-of-justice count where an evidence-tampering act was part of a wider effort to impede a criminal investigation or prosecution.
