"A person commits the federal crime of tampering with evidence when he or she knowingly alters, conceals, falsifies, or destroys any record, document, or tangible object with the intent to interfere with an investigation, possible investigation, or other proceedings by the federal government. (18 U.S.C. § 1519.) State laws also make it a crime to tamper with evidence in officials proceeding and investigations."
