21 F.4th 689
10th Cir.2021Background
- In 2018 Palms met M.W.; he then coerced, controlled, and prostituted her, taking her earnings and monitoring her communications.
- Police arrested M.W. during a prostitution sting; they arrested Palms in the parking lot and seized his cell phone.
- A Tulsa judge issued a warrant authorizing a search of Palms’s phone for “evidence of Human Trafficking,” listing broad categories of electronic data.
- Officers produced a physical, byte‑for‑byte extraction of the phone; investigators searched messages, photos, and emails focused on the relevant time period and stopped when privileged material appeared.
- The district court denied Palms’s suppression motion and, before trial, excluded evidence of M.W.’s prior commercial sex activity under Federal Rule of Evidence 412.
- After a retrial the jury convicted Palms on sex‑trafficking, attempted obstruction, and transporting for prostitution; Palms appealed the warrant/search and Rule 412 ruling.
Issues
| Issue | Plaintiff's Argument (Palms) | Defendant's Argument (Government) | Held |
|---|---|---|---|
| Validity/particularity of warrant to search phone | Warrant was not sufficiently particular; “human trafficking” too broad and lacked statute citation | Warrant limited search to evidence of human trafficking and listed specific data types; statutory definition of human trafficking provided limiting principle | Warrant satisfied Fourth Amendment particularity; limiting to evidence of human trafficking (under state statute) was sufficiently specific |
| Reasonableness of extraction and search of phone data | Physical, full extraction and review were overbroad and unreasonable; officers could have limited extraction or sought assistance | Extraction was necessary after logical/file extractions failed; searching was limited by time period and file types; officers acted reasonably and stopped at privileged material | Physical extraction and the search methodology were reasonable under the Fourth Amendment; suppression denial affirmed |
| Exclusion under Fed. R. Evid. 412 of victim's prior commercial sex work | Evidence that M.W. previously engaged in or knew how to post ads was critical to show recruitment/consent and impeach credibility (constitutional right to present a defense) | Prior commercial sex work is irrelevant to whether the later conduct was by force/coercion; Rule 412 protects against this evidence; exclusion did not violate constitutional rights | Exclusion did not violate due process or Confrontation Clause; prior prostitution was not probative of coercion and was properly excluded under Rule 412 |
