338 F. Supp. 3d 1235
D.N.M.2018Background
- On March 24, 2018, DHS Special Agent Fernando Lozoya, working with a long‑used confidential source (CS), surveilled Francisco Ybarra Cruz based on CS information that Cruz was transporting methamphetamine from Arizona.
- Lozoya corroborated multiple CS details: Cruz was in a white pickup with an Arizona plate, was with a female and child, and later was located at an O’Reilly’s and towing a black Ford with a Kansas plate.
- Lozoya directed New Mexico State Police Officer Leo Palomares to stop Cruz when Cruz entered I‑25; Lozoya had continuous surveillance and instructed Palomares to stop for any visible traffic violation.
- Palomares observed Cruz straddling the dotted line between the right travel lane and the Doña Ana exit lane and initiated a traffic stop.
- A subsequent dog‑sniff revealed ~11.5 pounds of methamphetamine; Cruz was Mirandized, waived rights, and made inculpatory statements. Cruz moved to suppress the evidence and statements as the product of an unlawful stop.
- The court held an evidentiary hearing and denied Cruz’s motion to suppress, finding the stop constitutionally reasonable.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether the traffic stop was supported by reasonable suspicion | Cruz: Officer Palomares lacked individualized reasonable suspicion to seize him | Government: Lozoya had reasonable suspicion based on CS corroboration and surveilled behavior; Palomares acted on Lozoya's instruction | Stop upheld — Lozoya had reasonable suspicion and that suspicion was imputed to Palomares under collective knowledge doctrine |
| Whether collective knowledge/vertical imputation justified the stop | Cruz: Stop must be justified by the stopping officer's own knowledge | Government: Lozoya’s reasonable suspicion may be imputed to Palomares who acted at Lozoya’s direction | Held for Government — vertical collective knowledge applies where an officer with reasonable suspicion directs another to stop |
| Whether Cruz violated NMSA §66‑7‑317(A) (failure to maintain lane) | Cruz: Towing another truck at night and unfamiliarity with I‑25 explain brief straddling; no statutory violation | Government: Palomares observed Cruz straddle the lane line for seconds with ~1/4 of vehicle over the line and no excusing conditions | Held for Government — under the totality of circumstances Palomares had reasonable suspicion of a lane violation |
| Whether, if statutory violation uncertain, the stop was reasonable under Heien (reasonable mistake of law) | Cruz: Statute requires fact‑specific inquiry; stop unreasonable if statute not violated | Government: Even if statutory application was ambiguous, officer reasonably (objectively) believed a violation occurred | Held for Government — even if statutory application was debatable, officer could reasonably err under Heien and act constitutionally |
