The crime of planting evidence doesn’t have a single name. Depending on the facts, prosecutors charge it as tampering with evidence, fabricating evidence, or obstruction of justice, and when a police officer is the one who did it, federal civil rights charges stack on top. Federal maximums reach 20 years in prison for the tampering offenses alone, and longer when force or injury is involved.
The Charges Prosecutors Actually Use
Because planting evidence describes conduct rather than a specific statute, the charge depends on which law best fits what happened. Three offenses do most of the work.
Tampering with evidence covers altering, hiding, or destroying a record, document, or physical object to undermine its reliability or keep it out of an investigation. Federal regulations define the offense as removing or concealing an item “with purpose to impair its verity or availability” in a pending or anticipated proceeding.1eCFR. 25 CFR 11.440 – Tampering With or Fabricating Physical Evidence
Fabricating evidence means creating something that never existed and presenting it as real. The same federal regulation reaches anyone who “makes, presents or uses any record, document or thing knowing it to be false” to mislead an official engaged in an investigation.1eCFR. 25 CFR 11.440 – Tampering With or Fabricating Physical Evidence
Obstruction of justice is a broader umbrella covering any illegal effort to interfere with a government proceeding. Planting evidence fits because it distorts the information available to investigators and courts.
These charges often overlap. Dropping a bag of drugs into someone’s car during a traffic stop could support tampering, fabrication, and obstruction all at once. Prosecutors generally pick whichever charge carries the strongest penalties given the facts.
Federal Penalties
Two federal statutes drive the heaviest sentences. Under 18 U.S.C. § 1519, anyone who knowingly falsifies a record, document, or physical object to obstruct a federal investigation faces up to 20 years in prison, a fine, or both.2Office of the Law Revision Counsel. 18 U.S. Code 1519 – Destruction, Alteration, or Falsification of Records in Federal Investigations and Bankruptcy The statute is broad enough to cover everything from planting a weapon at a crime scene to forging a document submitted to a federal agency.
The companion statute, 18 U.S.C. § 1512(c), targets anyone who corruptly alters, destroys, or conceals an object to impair its use in an official proceeding. The maximum is also 20 years.3govinfo. 18 U.S. Code 1512 – Tampering With a Witness, Victim, or an Informant Section 1512 climbs higher when physical force or threats are used to make someone else conceal or alter evidence; in that scenario the maximum sentence is 30 years.4Office of the Law Revision Counsel. 18 U.S. Code 1512 – Tampering With a Witness, Victim, or an Informant
State laws stack their own penalties on top, and they vary. Most states classify evidence tampering as a felony, with the grade and sentencing range turning on jurisdiction, the type of evidence involved, and whether the defendant is a private citizen or a government official.
When a Police Officer Plants Evidence
Officers face a layer of exposure civilians don’t. Beyond state tampering charges, a police officer who plants evidence can be prosecuted under 18 U.S.C. § 242, which makes it a federal crime for anyone acting “under color of any law” to willfully deprive a person of their constitutional rights. The baseline penalty is up to one year in prison. If the planted evidence leads to bodily injury, the maximum rises to 10 years. If someone dies as a result, the penalty can reach life in prison or death.5Office of the Law Revision Counsel. 18 U.S. Code 242 – Deprivation of Rights Under Color of Law
The career consequences are separate from the criminal case. Every state has a licensing body, often called a Peace Officer Standards and Training commission, that can revoke an officer’s certification for serious misconduct, including dishonesty. These agencies use a “clear and convincing” evidence standard, which is a higher bar than ordinary workplace discipline. Revocation means the officer can no longer work in law enforcement anywhere in that state. The National Decertification Index then tracks that revocation across state lines, so a decertified officer cannot quietly relocate and get rehired.
What Happens to a Case Built on Planted Evidence
If planting is discovered during or after a prosecution, several doctrines can take the case apart.
The Exclusionary Rule
The exclusionary rule bars the government from using evidence obtained in violation of the Constitution. In Mapp v. Ohio, the Supreme Court held that evidence gained through an unreasonable search or seizure cannot be presented in court.6Constitution Annotated. Amdt4.7.1 Exclusionary Rule and Evidence Planted evidence is unconstitutional on its face because it manufactures a basis for prosecution that never legitimately existed. Once a court finds that evidence was planted, that evidence is suppressed, and if the case depended on it, the charges are often dismissed.
Franks Hearings
Sometimes planted material is used to get a search warrant, and the real evidence turns up during the resulting search. In that situation a defendant can ask for a Franks hearing. In Franks v. Delaware, the Supreme Court held that when a defendant makes a substantial preliminary showing that a false statement was knowingly or recklessly included in a warrant application, and that false statement was necessary to establish probable cause, the defendant is entitled to a hearing to challenge the warrant.7Justia Law. Franks v. Delaware, 438 US 154 (1978) If the defendant prevails, the warrant is voided and the evidence obtained through it is thrown out.
Brady Violations
Under Brady v. Maryland, prosecutors must turn over any evidence favorable to the defense. The Court held that “suppression by the prosecution of evidence favorable to an accused upon request violates due process where the evidence is material either to guilt or to punishment.”8Library of Congress. Brady v. Maryland, 373 US 83 (1963) When an officer plants evidence and the prosecution knows or should know, failing to tell the defense is a Brady violation. That can be grounds to overturn a conviction on appeal, even years later.
Suing for Damages After the Fact
A person who was wrongfully charged or convicted because of planted evidence can sue the responsible officials under 42 U.S.C. § 1983. The statute lets anyone whose constitutional rights were violated by a person acting under government authority file a federal civil suit for money damages.
Winning is not simple. A plaintiff generally has to show that the official knowingly or recklessly submitted false evidence and that there is a reasonable likelihood the plaintiff would not have been charged without it. Timing matters too. The statute of limitations on a fabricated-evidence claim does not start running until the underlying criminal case ends in the plaintiff’s favor, so if it takes years to get a conviction overturned, the civil clock doesn’t begin until then.
Damages can be substantial. A successful § 1983 plaintiff can recover for time spent in prison, lost income, emotional distress, and legal fees. Most states do not cap damages in federal civil rights cases, and awards in wrongful conviction suits routinely reach into the millions.
If You Think Evidence Was Planted
Timing and documentation matter more than anything else.
- Get a criminal defense attorney immediately. A lawyer can file a motion to suppress and, where warranted, request a Franks hearing to challenge any warrant that relied on the planted material.
- Preserve everything that could contradict the evidence or establish your whereabouts: surveillance footage, text messages, GPS data, witness contact information. Records disappear quickly.
- File a formal complaint with the law enforcement agency’s internal affairs division if a police officer is involved. That creates an official record even if the internal review moves slowly.
- Report to the FBI or the local U.S. Attorney’s Office. The Department of Justice directs civil rights misconduct complaints to the FBI for criminal investigation and to the U.S. Attorney, both of which have offices in most major cities.9U.S. Department of Justice.

Planted evidence that goes unchallenged becomes the foundation of a conviction, and unwinding a conviction after the fact is far harder than fighting the evidence in real time.
