718 F.3d 568
6th Cir.2013Background
- Federal agents tracked Rivas from Texas to Memphis suspecting drug trafficking.
- Rivas met Figueredo-Diaz and Morales-Loya; they traveled in multiple vehicles, including a tractor-trailer.
- Narcotics dog alerted to drugs in the trailer during a search while Rivas was at large.
- A large quantity of marijuana was found hidden under the trailer floor; cash and Figueredo-Diaz’s documents were seized.
- District court suppressed the marijuana evidence as to Figueredo-Diaz and Morales-Loya but not for Rivas.
- This interlocutory appeal challenges the suppression ruling as to Figueredo-Diaz and Morales-Loya.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether the detention of Figueredo-Diaz and Morales-Loya caused the discovery of evidence | Figueredo-Diaz and Morales-Loya detention led to evidence | Detention was unlawful and caused the discovery | No; detention did not cause discovery of evidence |
| Whether the inevitable-discovery doctrine applies | Evidence would inevitably be discovered | No causal link from unlawful detention to discovery | Inevitable discovery not applicable; no but-for causation from detention |
| Whether the suppression was warranted under deterrence principles | Suppression deters future violations | Deterrence not served; evidence would be found anyway | Deterrence not satisfied; suppression not warranted |
