Background

Oliver Matheny entered a conditional guilty plea to producing child sexual abuse material in violation of 18 U.S.C. § 2251(a) and (e). He reserved the right to challenge the denial of his motion to suppress evidence recovered from a SanDisk Secure Digital card.

A witness gave the SD card to law-enforcement officers and said she had viewed its contents. She described videos showing partially clothed minor females using the bathroom at Matheny’s residence. Although the district court found the warrant authorizing the officers’ search invalid, it concluded that the evidence was admissible under the private-search doctrine.

The Court’s Holding

The Fourth Circuit affirmed. It explained that the Fourth Amendment regulates governmental searches, not searches conducted by private individuals acting in a private capacity. Government officers may repeat a private search without triggering the Fourth Amendment so long as they do not exceed its scope and invade a privacy interest that the private search did not already frustrate.

The witness said she had viewed the SD card and specifically described the videos she saw. At the suppression hearing, an investigating officer confirmed that the card contained videos matching that description. The court concluded that the officer did not learn anything of significance beyond what the witness’s private search had already revealed, so the district court properly denied suppression despite the invalid warrant.

Key Takeaways

  • Evidence discovered through a private individual’s search is not excluded merely because that private search may have been unlawful.
  • A subsequent government search must remain within the scope of the earlier private search and must not reveal significant information that the private search had not already exposed.
  • The witness’s detailed description of the SD-card videos supported the finding that the officer’s examination did not create an additional Fourth Amendment intrusion.

Why It Matters

The unpublished decision illustrates how the private-search doctrine can independently support admission of digital evidence when a search warrant is invalid. In evaluating a government examination of a device previously searched by a private person, courts will compare what the private person reported seeing with what investigators later discovered.
