State v. Monafo, 384 P.3d 134

On July 1, 2011, deputy Seely stopped Monafo for a traffic violation while he was towing a van. Seely released Monafo and left the scene.
A bystander, Francisco Castro, told other officers he owned the van and had not consented to its removal; Seely, returning after he had left, re‑stopped Monafo moments later.
Seely requested a bill of lading/manifest for the van; Monafo produced a receipt book and opened it to the relevant receipt for the van, which Seely examined and ran a license check on.
While holding the receipt book, Seely walked to the rear of the truck and leafed through other receipts in the book, discovering inconsistent signatures and a license number that did not match the named owner; Seely then arrested Monafo for unlawful taking of a vehicle.
Monafo challenged (1) attenuation between the first (found unconstitutional) stop and the second stop/search (fruit of the poisonous tree), (2) the scope of consent to search the receipt book, and (3) whether the van qualified as a “vehicle” under the Motor Vehicle Code; he entered a conditional plea reserving appeal rights.
The Court of Appeals held the second stop was sufficiently attenuated from the first but concluded Seely exceeded the scope of Monafo’s consent by inspecting receipts beyond the single page for the van; all receipts except the van receipt must be suppressed and the case was remanded to allow Monafo to withdraw his plea if he chooses.

Issue	State's Argument	Monafo's Argument	Held
Whether evidence from the second stop is barred as fruit of an earlier unconstitutional stop	Attenuation existed (release, Monafo began to leave, Castro’s arrival was intervening) so evidence admissible	Second stop/search flowed directly from the illegal first stop and must be suppressed	Attenuation present; evidence from second stop not excluded on that basis
Whether Monafo consented to a search of the entire receipt book or only the single receipt for the van	Consent was not limited by Monafo’s silence/possession; handing over the book supported broader inspection	Consent was limited to the single receipt produced for the van	Consent was limited to the van receipt; Seely impermissibly expanded the search; suppress all other receipts
Whether the van is a “vehicle”/“motor vehicle” or a “nonrepairable vehicle” under the Motor Vehicle Code (affecting charge)	State: record supports treating the van as a vehicle for purposes of the unlawful‑taking statute	Monafo: van may be a nonrepairable vehicle excluded from the statute	Factual question for the jury; district court properly denied pretrial dismissal
Remedy after partial suppression (receipt book)	N/A (State defended admissibility)	If suppression successful, defendant should be allowed to withdraw conditional plea	Court partially reverses suppression ruling and remands so Monafo may withdraw plea if he chooses
