94 F.4th 321
4th Cir.2024Background
- Six members of MS-13 were convicted after a seven-day trial for sex trafficking a 13-year-old girl, conspiracy to do so, and related federal crimes across Virginia and Maryland.
- The crimes involved abduction, beatings, prolonged confinement, sexual exploitation, threats, and trafficking of the minor by force and coercion.
- Federal investigation relied heavily on evidence obtained from four sequential Facebook warrants, seeking user data and communications to uncover conspiratorial activities.
- Five defendants moved to suppress Facebook-derived evidence, arguing the warrants lacked probable cause and particularity as required by the Fourth Amendment. The sixth challenged the sufficiency of the evidence against him.
- The district court denied all suppression and acquittal motions, finding the warrants constitutional and the evidence at trial ample.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Probable cause for the Facebook warrants | No probable cause (insufficient nexus to the accuseds) | Warrants supported by case-specific affidavits, training | Magistrates had substantial basis for probable cause |
| Particularity of the Facebook warrants (scope) | Warrants overbroad—too many categories of data sought | Scope was limited by reference to specific offenses | Warrants were sufficiently particularized in scope |
| Particularity (temporal limitation) | Warrants should have been time-limited to the trafficking | Broader timeframes justified by ongoing, complex conspiracy | Warrant periods were reasonable or saved by good faith |
| Sufficiency of evidence vs. Gutierrez Castro | Insufficient evidence for conviction | Substantial testimonial and Facebook evidence supported guilt | Ample record supported conviction; acquittal denied |
