§3600A Preservation of Biological Evidence

Title 18 › PART II — CRIMINAL PROCEDURE › CHAPTER 228A — POST-CONVICTION DNA TESTING › § 3600A

Last updated Sep 22, 2026|Official source

Summary

The Government must keep biological evidence collected in a federal criminal case when the person convicted is sent to prison. Biological evidence means a sexual assault forensic exam kit or things like semen, blood, saliva, hair, skin tissue, or other identified body material. The duty to keep evidence does not apply if, after all direct appeals are finished, the defendant is told the evidence may be destroyed and does not file a motion under section 3600 within 180 days of that notice; or if the item must be returned to its owner or is too large to keep but the Government reasonably saves pieces big enough for future DNA testing; or if DNA testing under section 3600 already showed the defendant as the source. The Attorney General had to make rules to enforce this within 180 days of the Innocence Protection Act of 2004. Anyone who knowingly destroys or tampers with required biological evidence to stop DNA testing or its use in a proceeding can be fined, jailed up to 5 years, or both. This rule does not create a basis for relief in federal habeas corpus.

(2)(A)the evidence must be returned to its rightful owner, or is of such a size, bulk, or physical character as to render retention impracticable; and
