76 F.4th 788
8th Cir.2023Background
- Joshua Duggar was linked to hundreds of child‑pornography downloads traced to a computer at a used‑car dealership he owned; agents executed a federal search warrant at the dealership.
- During the search agents seized Duggar’s phone after he said he wanted to call an attorney; while speaking to agents he volunteered that he was familiar with file‑sharing software and had installed it on his devices, including the office computer.
- A grand jury indicted Duggar for possessing and receiving child pornography; at trial metadata from Duggar’s iPhone placed the phone at the dealership at the time of the downloads.
- The district court excluded evidence that a former employee (a convicted sex offender) committed the offense and barred impeachment of that employee with his prior sex‑offense conviction.
- Duggar moved to suppress his on‑scene statements as an invocation of counsel; the district court denied suppression and allowed the government’s forensic expert to testify about EXIF/GPS metadata while limiting Duggar’s expert from opining about dates/times she had not examined.
- The jury convicted Duggar; he was sentenced to 151 months. On appeal the Eighth Circuit affirmed the convictions and evidentiary rulings.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Exclusion of former employee’s prior sex‑offense conviction (right to present a defense) | Excluding impeachment evidence of the alternative perpetrator deprived Duggar of his Sixth/Fifth Amendment right to present a complete defense | District court properly excluded the conviction under Rule 403 to avoid unfair prejudice and juror confusion | Affirmed: exclusion within district court’s constitutional discretion under Rule 403; no constitutional violation |
| Suppression of statements invoking counsel (Miranda/custody) | Duggar invoked his right to counsel and attempted to call an attorney; statements should be suppressed | Encounter was noncustodial; Miranda protections had not attached | Affirmed: under Griffin factors a reasonable person would not have felt confined; no Miranda violation |
| Admissibility of government forensic analyst’s metadata testimony | Analyst lacked sufficient qualifications and methods to link EXIF/GPS metadata to Duggar’s phone/location | Analyst was experienced, examined raw EXIF data, and used verifiable mapping methods | Affirmed: district court did not abuse discretion under Rule 702/703; analyst qualified and methods reliably applied |
| Limits on defense expert’s testimony about EXIF dates/times | Court improperly precluded expert from challenging dates/times in metadata | Expert never loaded or verified the metadata; testimony would be speculative and confusing | Affirmed: district court properly limited speculative testimony under Rule 403 and Rules 702/703 |
