632 F. App'x 272
6th Cir.2016Background
- Federal indictment alleged large-scale sex-trafficking conspiracy; first trial involved nine defendants on counts under 18 U.S.C. § 1591 and related statutes; the trial lasted three weeks and resulted initially in mixed verdicts later vacated on conspiracy theory grounds.
- After the first trial the district court made several in-trial evidentiary rulings that the government sought to revisit pre‑trial for subsequent defendants; the government appealed those rulings under 18 U.S.C. § 3731.
- Three recurring questions were presented: whether § 1591 applies only to child victims; the meaning/scope of “venture” in § 1591(a)(2); and whether teachers and police officers must be treated as experts when opining about a person’s age under Fed. R. Evid. 701(c).
- At trial the prosecution had attempted to use brief testimony by police and lay witnesses showing mere association (traffic stops, dining together) to prove a § 1591 “venture,” and sought teacher/police testimony about the victim’s age without disclosing them as experts.
- The district court (1) held § 1591 applies only to trafficking of children, (2) ruled “venture” must be tied to sex‑trafficking activity (mere association insufficient), and (3) excluded testimony from teachers and officers that the court viewed as relying on specialized vocational knowledge without expert disclosure.
Issues
| Issue | Government's Argument | Defendants' Argument | Held |
|---|---|---|---|
| Does § 1591(a) criminalize sex‑trafficking of adults as well as children? | § 1591 covers adult victims when trafficking is effected by force, fraud, or coercion; the statute’s text and subparts support that reading. | § 1591 applies only to children because § 1591(b) lacks a punishment provision for ordinary adult prostitution. | Reversed district court: § 1591 criminalizes sex‑trafficking of children without force/fraud/coercion and adults when trafficking is effected by force, fraud, or coercion. |
| What is a “venture” under § 1591(a)(2)? | "Venture" is statutorily defined as any group of two or more associated in fact; government may use evidence of association even if association has other, non‑trafficking purposes. | "Venture" must be a sex‑trafficking venture; mere association or membership (e.g., dining together, traffic stops, gang membership, soccer team) is insufficient—prosecution must show participation that furthers sex‑trafficking. | Affirmed district court: “venture” must be tied to sex‑trafficking activity; mere association or unrelated membership is irrelevant and may be excluded. |
| Are teachers and police officers automatically lay witnesses for age opinions under Fed. R. Evid. 701(c)? | Vocational experience of teachers/officers in judging age is within common perception and therefore may be admissible as lay opinion without expert disclosure. | Such testimony, when based on specialized vocational experience beyond jurors’ common knowledge, is expert testimony under Rule 702 and impermissible without disclosure. | Affirmed (with clarification): Court may exclude testimony that is presented or based on specialized vocational knowledge under Rule 701(c)/702; teachers/officers are not per se experts but their testimony may require expert disclosure if it relies on specialized occupational knowledge or is presented as expert opinion. |
