The Damp Phone and the Renamed Video
Denny Arceneaux is investigating a suspected staged collision in Shreveport for an auto insurer. A tow-truck operator hands him the SD card from his dash camera, which recorded the impact. Denny copies the files onto his laptop, renames the main clip "evidence_final.mp4," and returns the card to the operator. He photographs several Facebook Marketplace listings for the same damaged parts, screenshots them, and texts the images to the adjuster. He also obtains text messages from the claimant's ex-girlfriend, who hands him her own phone and consents to his reading it.
Two weeks later, after dropping his phone in a puddle, Denny writes his report from memory. The file is stored in a shared Dropbox folder the adjuster and two claims assistants can open. Nothing in the file records who handled the SD card, when, or whether the video was altered. The insurer's counsel is preparing for a civil fraud trial and asks whether the video will come in.
1. Identify the chain-of-custody and authentication defects in the video handling, and explain how the insurer can still get the video admitted.

Defects. The original card went back to a third party with no image, no hash, and no log. The file was renamed, which alters metadata and signals handling. There is no record of who copied it, using what, or whether the copy was made with write protection. Storage in a shared cloud folder with three users and no access log creates an obvious tampering argument. Best practice is: inventory the item, image it with a documented tool, compute a SHA-256 hash at acquisition, log every transfer with date, time, custodian, and purpose, and store the original in a sealed, access-controlled location. Produce only copies, with the hash attached to the production.
Authentication. Under La. C.E. art. 901, the proponent must produce evidence sufficient to support a finding that the item is what it purports to be. Two routes exist. Under the pictorial testimony approach, the tow operator or another witness who saw the collision testifies that the video fairly and accurately depicts the scene. Under the silent witness approach, the proponent must show the reliability of the camera system: who owned it, how it was mounted, how it recorded, whether the time and date were set correctly, and that no one had the opportunity to alter the file.
Cure. Get a signed affidavit or declaration from the tow operator describing how the card was pulled and that the footage was not edited; recover the card if it still exists and re-image it; produce the hash and the acquisition log now, even if created late, with a candid explanation of the lapse; and have the operator available live. The best-evidence rule (La. C.E. arts. 1002–1003) permits duplicates absent a genuine question about authenticity - but the renaming and the shared folder are precisely what creates that question, so expect a fight.
2. Analyze the text-message evidence from the ex-girlfriend's phone: access, privacy, authentication, and hearsay.

Access. The ex-girlfriend can consent to a search of her own device; sharing a conversation one participated in is generally not itself unlawful. The Stored Communications Act reaches providers, not a device owner who consents, so reading her phone is not an SCA violation. Two traps: if the messages had instead been pulled from the claimant's cloud backup or from an account she did not own, that is unauthorized access with criminal and civil exposure; and content unrelated to the case must be screened out, or the investigator invites an intrusion-upon-seclusion claim.
Preservation. Denny should have photographed the phone screen showing the contact name and number, captured the message thread in sequence, and documented the device's identifying information. Screenshots texted to an adjuster and stored in a shared folder are a weak copy. The phone itself should be preserved or imaged.
Authentication. Someone must testify about how the messages were obtained and who the sender was. Identity is the vulnerable point - a contact label is not proof that the claimant typed the words. Corroboration helps: the claimant's known number, replies that reference facts only he knew, and phone records tying the number to him at the times of the messages.
Hearsay. The claimant's own messages are opposing-party statements under La. C.E. 801(D)(2) and come in when offered against him. The ex-girlfriend's messages are not; they need a separate exception, and if the insurer offers them to prove the truth of what she said, they may be excluded. The report should quote only what is needed and label each message by sender.
3. Denny's report was written twelve days after the fact from memory after his notes were destroyed. What should he do now, and what should the report itself contain?

Do not reconstruct silently. He must not rewrite notes and present them as contemporaneous. Instead, prepare a written memorandum describing the loss - when the phone was damaged, what it contained, what recovery attempts were made (cloud backup, carrier records, laptop sync), and what was irretrievable. Disclose it to counsel and expect to produce it. Concealment of a lost-notes problem is a credibility catastrophe on cross-examination and a board issue; disclosure is survivable.
Rebuild from independent anchors. Timestamped video, the dash-cam file metadata, his phone's call and location logs, the tow operator's records, the Marketplace screenshots with their capture times, and his correspondence with the adjuster. Each reconstruction should cite the underlying source rather than memory, and the report should state clearly which facts are reconstructed and from what.
Report structure. Identify the investigator and license number; state the assignment and scope; list evidence reviewed with an exhibit index and hash values; give a chronological narrative of observed facts in plain past tense; separate observations from analysis under a distinct heading; identify persons interviewed and whether the interview was recorded; state limitations, including the lost notes and any gaps in the video; include no conclusions about guilt; and attach the custody log. Use consistent date and time references and never quote a statement without the recording or note source.
Retention. Put the file under a litigation hold, freeze the Dropbox folder, and stop texting excerpts to the adjuster. In litigation, every casual message becomes an exhibit.
