If a package containing a forensic kit, specimen, case file, or other sensitive material goes missing, treat it as both a delivery problem and a possible chain-of-custody or privacy incident. For U.S. consumers, preserve the records, notify the sender or agency responsible for the contents, and use the USPS, carrier, law-enforcement, or payment process that fits the facts.

Don't open a recovered package, make a bait shipment, confront a suspected thief, or assume the loss automatically ends a criminal case.

Identify who had responsibility for the package

The correct next step depends on who controlled the item when it disappeared.

"Evidence package theft" isn't a single national reporting category. A missing police exhibit, a stolen mailed laboratory kit, an undelivered consumer order, and tampering by an employee can involve different facts and different laws.

What to do as soon as a package goes missing

1. Save delivery records. Download the tracking history, delivery photographs, order confirmation, shipping label, emails, and text alerts. Write down when you noticed the loss.
2. Check the delivery details. Confirm the address, read any delivery notice, and ask household members, neighbors, or the mailroom whether they accepted the package. A package marked delivered may have been left in another secure location.
3. Preserve video. Save the original camera file if possible, along with a copy that shows the date and time. Don't edit, crop, or overwrite the original.
4. Notify the sender or responsible organization. The sender may be the customer, laboratory, agency, or merchant that can open a carrier investigation or insurance claim.
5. Report suspected theft. For a break-in or theft from your property, use local law enforcement's non-emergency reporting channel unless someone is in immediate danger. If you suspect stolen mail or misconduct by a USPS employee or contractor, use the reporting route described by the USPS Office of Inspector General.

Don't post an address label, case number, medical information, or identifiable security footage online. Those details may expose private information and interfere with an investigation.

If the package was sent through USPS

Start with the official USPS Missing Mail process. USPS explains what information to provide for a search request and says it sends a confirmation email after receiving the request.

An insured shipment may qualify for an insurance claim, depending on the service used. A service with a money-back guarantee, such as Priority Mail Express, may also have a refund process. Neither option guarantees that the package will be found or that a claim will be paid. Ask the sender which claim route applies and whether the sender or recipient must submit it.

Give the sender a copy of the tracking history and any theft report. If the package contained a forensic sample or official evidence, tell the responsible agency or laboratory exactly what was missing and whether the packaging may have been exposed, opened, or damaged.

A Missing Mail search isn't a criminal investigation. If you believe the item was stolen, report that separately through the appropriate law-enforcement or USPS channel.

If a private carrier handled the shipment

Notify both the sender and the carrier. Use the carrier's official investigation or claim process, keep the claim or report number, and provide the tracking history, delivery details, photographs, and any theft report.

Claim deadlines, eligible claimants, and reimbursement terms can vary by carrier and service. Don't assume that USPS rules apply to a private shipment. If the contents were official evidence or a laboratory specimen, notify the agency or laboratory even if the carrier is still investigating.

If the evidence was already in official custody

Consumers generally shouldn't try to reconstruct a chain of custody themselves. Contact the agency's property or evidence unit, the assigned investigator, or the prosecutor's office. A victim advocate may help a victim or witness find the right contact.

Ask for:

• The incident or case number
• The evidence or package identifier
• The last documented location or transfer
• Whether the package was sent to a laboratory
• Whether the prosecutor or court was notified
• Whether an internal incident report was created
• Whether video, access logs, and custody records are being preserved

Keep communications in writing when possible. Save names, dates, and the substance of phone calls in a timeline.

If the package is later found, don't open it, reseal it, clean it, or move it unnecessarily. Contact the responsible agency and explain where it was found. If you already handled it, report that accurately. Hiding the contact can create a larger chain-of-custody problem.

A missing item may affect an investigation or prosecution, but it doesn't automatically dismiss a case. Prosecutors and courts assess the significance and reliability of the remaining evidence under the rules that apply in that jurisdiction.

If you paid for an item that never arrived

Credit-card purchases

The Federal Trade Commission says that a credit-card charge for merchandise you never received can be challenged as a billing error. To use the federal billing-error procedure, send a written dispute so the card issuer receives it within 60 days after the first statement showing the error was sent.

Include:

• Your name and account information
• The transaction date and amount
• The merchant's name
• A short explanation that the item wasn't received
• Copies of the order, tracking history, and communications with the seller
• The correction or credit you're requesting

Send the letter to the issuer's billing-dispute address, not just the address used for payments. Keep a copy and proof of delivery.

The issuer must acknowledge the dispute in writing within 30 days unless it resolves the matter sooner. It must resolve the dispute within two billing cycles and no later than 90 days after receiving the letter. During the investigation, you generally don't have to pay the disputed amount or related finance charges, but you should continue paying amounts you aren't disputing.

Some issuers may extend the 60-day period when a shipment is delayed, but don't rely on an extension. The FTC's guidance on billing errors and unordered products sets out the required steps.

Orders that were never shipped

A delivery loss is different from a seller missing its shipping obligation. Under the FTC's Mail, Internet, or Telephone Order Merchandise Rule, a seller must have a reasonable basis to ship within the advertised period or, if no period was stated, within 30 days.

When the seller can't meet that deadline, it must obtain your consent to a shipping delay or refund payment for the unshipped merchandise. Ask the seller in writing whether the order shipped, request the tracking number, and state clearly whether you want to cancel and receive a refund.

Debit, prepaid, bank-transfer, and payment-app transactions

The federal credit-card billing-error procedure doesn't automatically apply to every payment method. Debit cards, prepaid cards, bank transfers, and person-to-person payment apps can have different protections and reporting deadlines.

Notify the provider immediately. Ask for its written dispute or fraud process, then submit the order confirmation, tracking history, communications, and theft report. Don't wait for the 60-day credit-card period if you used another payment method.

What evidence to keep

Create one folder containing:

• The order confirmation or transfer receipt
• Tracking numbers and status changes
• Shipping and delivery notifications
• Photos of the package, label, seal, or damage
• Original security-camera files
• Emails, chat messages, and call notes
• Police, USPS, carrier, or agency report numbers
• The name of every organization or person you contacted
• A list of sensitive information or materials inside the package

If the package contained medical, biometric, financial, or identifying information, ask the sender what may have been exposed and whether it has a privacy or breach-response process.

Treat statistics and penalty claims carefully

There is no single official U.S. measure for "evidence package theft." A porch-theft estimate, retail-loss figure, mail-fraud case, rape-kit backlog, or fingerprint success story doesn't measure theft of evidence packages. Claims about a universal recovery rate, investigation rate, or conviction percentage should identify a named study and a clearly defined category before you rely on them.

Criminal penalties require the same caution. Package theft, mail theft, evidence tampering, destruction of evidence, fraud, and obstruction are different legal questions. USPS involvement may create a federal reporting or investigative route, but it doesn't automatically make every incident a federal offense. A maximum sentence from one indictment isn't a general sentence for every missing package.

Relevant facts can include the carrier, location, ownership of the item, intent, access to official records, whether the package was opened or altered, and the state where the conduct occurred. For a case-specific assessment, speak with a qualified attorney or victim advocate in the relevant jurisdiction.

Common questions

Is stealing an evidence package always a federal crime?

No. The classification depends on the facts, the carrier, the location, and the conduct involved. A USPS-related incident may have a federal reporting route, but reporting it doesn't determine the eventual charge.

Does a missing forensic kit automatically invalidate a criminal case?

No. The effect depends on what the kit contained, how it was handled, whether it can be located, and what other evidence exists. The prosecutor and court, not the package recipient, decide how the loss affects the case.

Should I make a bait package to catch the thief?

No. A homemade bait package can create safety risks, expose private information, and interfere with an official investigation. Give tracking details and video to the appropriate agency instead.

Can I file a chargeback for a stolen evidence package?

Only if you paid for a consumer purchase and the transaction qualifies as a billing dispute. A credit-card dispute may address non-delivery, but it doesn't replace a theft report or repair a chain-of-custody problem.

Start by placing the tracking history, receipt, footage, and package details in one folder. Then contact the sender or responsible agency before submitting the USPS, carrier, or payment report that matches the loss.
