1. PRELIMINARY STATEMENT
1.1 This Motion is timely filed under the scheduling order entered on [DATE] and Rule 12(b)(3) and (d) of the Wyoming Rules of Criminal Procedure, which require that a motion to suppress evidence be raised before trial by the deadline set by the court, absent a showing of good cause for a later filing.
1.2 Suppression is constitutionally mandated because law-enforcement officers obtained the evidence at issue through methods that violated Defendant’s federal and state constitutional rights, as further detailed herein.
2. STATEMENT OF RELEVANT FACTS
2.1 On [DATE] at approximately [TIME], officers with the [LAW-ENFORCEMENT AGENCY] entered [LOCATION] without a warrant.
2.2 Officers allegedly relied on [BASIS ASSERTED FOR ENTRY—e.g., “consent,” “exigent circumstances,” or “anonymous tip”].
2.3 While inside, officers conducted a search and seized [DESCRIPTION OF ITEMS] (collectively, the “Subject Evidence”).
2.4 Defendant was placed in custody and interrogated without being advised of constitutional rights until [TIME], after inculpatory statements were elicited.
2.5 A search warrant was later sought and issued based, in substantial part, on information derived from the initial unlawful entry and the unwarned statements.
2.6 The State intends to introduce the Subject Evidence and Defendant’s statements at trial.
3. APPLICABLE LEGAL STANDARDS
3.1 Constitutional and State Grounds
• U.S. Const. amend. IV safeguards individuals against unreasonable searches and seizures.
• U.S. Const. amend. XIV makes those protections applicable to the States.
• Wyo. Const. art. 1, § 4 provides co-extensive—and in some instances broader—protections.
3.2 Wyoming Suppression Framework
Under Wyoming law, a defendant may move to suppress evidence obtained in violation of constitutional guarantees. The State bears the burden of proving by a preponderance of the evidence that the challenged search or seizure was lawful.
3.3 Good-Faith Exception Parameters
The United States Supreme Court has recognized a good-faith exception to the federal exclusionary rule for evidence obtained through an officer's objectively reasonable reliance on a search warrant later found to be invalid. See United States v. Leon, 468 U.S. 897 (1984). The Wyoming Supreme Court, however, has emphasized that Article 1, Section 4 of the Wyoming Constitution provides protections independent of, and in some respects broader than, the Fourth Amendment—including a heightened affidavit requirement and a "reasonable under all the circumstances" standard that permits inquiry into an officer's actual intent. See O'Boyle v. State, 2005 WY 83, 117 P.3d 401 (Wyo. 2005); Pierce v. State, 2007 WY 182, 171 P.3d 525 (Wyo. 2007). Counsel should confirm, at the time of filing, whether the Wyoming Supreme Court has since squarely adopted, limited, or declined to adopt a good-faith exception to the exclusionary remedy under the state constitution, and should not assume the federal Leon framework applies without independent verification of current Wyoming law.
4. ARGUMENT
4.1 Warrantless Entry & Search Without Probable Cause
4.1.1 Warrantless searches inside a residence are presumptively unreasonable absent a specifically established exception.
4.1.2 The officers’ claimed [EXCEPTION] is unsupported by articulable facts demonstrating probable cause and exigency.
4.1.3 All evidence observed or seized during the unlawful intrusion, including officers’ subsequent observations forming probable cause for the warrant, must be suppressed.
4.2 Invalid Search Warrant Lacking Particularity/Probable Cause
4.2.1 The subsequently issued warrant was predicated on tainted information, rendering the warrant and resultant search invalid.
4.2.2 Even if independent information existed, the warrant failed to describe the place to be searched and items to be seized with requisite particularity.
4.2.3 Suppression is required because no meaningful attenuation or independent source can purge the taint.
4.3 Unlawful Custodial Statements (Miranda)
4.3.1 Defendant was subjected to custodial interrogation without being advised of rights.
4.3.2 Statements obtained are inadmissible, and any evidence derived therefrom is fruit of the poisonous tree.
4.4 Fruits of the Poisonous Tree
4.4.1 Evidence discovered as a direct or indirect result of the constitutional violations is inadmissible unless the State meets its heavy burden to show attenuation, independent source, or inevitable discovery—none of which is present here.
4.5 Inapplicability of Any Good-Faith Exception
4.5.1 Even assuming a good-faith exception applies under Wyoming law, officers could not have reasonably relied on a warrant grounded in unlawfully obtained information.
4.5.2 Any suggestion that officers acted in “objectively reasonable” reliance is rebutted by their prior unconstitutional conduct and facial deficiencies in the warrant.
4.5.3 Because Article 1, Section 4 of the Wyoming Constitution may afford broader protection than the Fourth Amendment, Defendant further contends that no good-faith exception should excuse the constitutional violations described herein.
5. REQUEST FOR EVIDENTIARY HEARING
Defendant requests a full evidentiary hearing under Rule 12(b)(3) and (j) to determine the admissibility of the Subject Evidence and to allow for presentation of testimonial, photographic, and documentary evidence regarding the circumstances of the search, seizure, and interrogation.
6. RESERVATION OF RIGHTS
Defendant expressly reserves the right to supplement, amend, or renew this Motion should additional facts become known or legal authority evolve before trial.
7. PRAYER FOR RELIEF
WHEREFORE, Defendant respectfully requests that this Court:
A. Conduct an evidentiary hearing at the earliest practicable date;
B. Suppress the Subject Evidence, all statements obtained from Defendant, and any derivative evidence;
C. Preclude the State from referencing or introducing the suppressed evidence at any stage of the proceedings; and
D. Grant such other and further relief as justice may require.
Respectfully submitted this ___ day of __________, 20__.
8. CERTIFICATE OF SERVICE
I certify that a true and correct copy of the foregoing Motion to Suppress Evidence was delivered to the Office of the [COUNTY] County and Prosecuting Attorney, on this ___ day of __________, 20__, via [e-mail/hand delivery/e-filing], pursuant to Rule 49 of the Wyoming Rules of Criminal Procedure and Rule 5 of the Wyoming Rules of Civil Procedure (governing service in criminal proceedings).

Criminal law paperwork covers every stage of a criminal case, from the first appearance and bail motion through pretrial motions, plea agreements, sentencing, and appeals. Deadlines in criminal cases are short and often unforgiving, and constitutional rights can be waived just by missing a filing. Using the right motion at the right time can mean the difference between evidence getting suppressed, charges getting reduced, or a case getting dismissed entirely.
