AFFIDAVIT IN SUPPORT OF SEARCH WARRANT

IN THE UNITED STATES DISTRICT COURT

FOR THE WESTERN DISTRICT OF MISSOURI

I, , being duly sworn, state the following is true and correct to the best of my knowledge and belief:

INTRODUCTION

1. I have been employed as a Special Agent (SA) with the Federal Bureau of Investigation (FBI) for over years. I have investigated matters involving the criminal infringement of a copyright, particularly in relation to violations of Title 18, United States Code, Section 2319, which criminalizes, in part, the reproduction or distribution of copyrighted works.

2. The location to be searched is known as , , Missouri 64730, and this affidavit is submitted in support of a warrant to search the entire premises, including any business records and any computer

and computer media located therein where the instrumentalities, fruits, and/or evidence of violations of Title 18, United States Code, Section 2319, as specified further in Attachment A, might be found.

3. The statements contained in this affidavit are based on information provided by the Butler Missouri Police Department (BPD), as well as my experience and background as an Agent with the FBI. Set forth in this affidavit are the facts I believe are necessary to establish probable cause to believe that evidence of violations of Title 18, Unites States Code, Section 2319, are located at the above address.

DEFINITIONS

4. The term "computer," as used herein, is defined pursuant to Title 18, United States Code, Section 1030(e)(1), as "an electronic, magnetic, optical, electrochemical, or other high speed data processing device performing logical or storage functions, and

includes any data storage facility or communications facility directly related to or operating in conjunction with such device."

5. The terms "records," "documents," and "materials" include all information recorded in any form, visual or aural, and by any means, whether in handmade form (including, but not limited to, writings and drawings), photographic form (including, but not limited to, microfilm and photocopies), mechanical form (including, but not limited to, records, printing, typing) or electrical, electronic or magnetic form (including, but not limited to, compact discs, electronic or magnetic storage devices such as floppy diskettes, hard disks, CD-ROMs, digital video disks (DVDs), Personal Digital Assistants (PDAs), memory sticks, optical disks, smart cards, or electronic notebooks, as well as digital data files and printouts or readouts from any magnetic, electrical or electronic storage device).

SPECIFICS OF SEARCHES AND SEIZURES OF COMPUTER SYSTEMS

6. I have consulted with an expert in computer searches, Computer Specialist/Forensic Examiner . According to CS/FE searching

and seizing information from computers often requires agents to seize all electronic storage devices (along with related peripherals) to be searched later by a qualified computer expert in a laboratory or other controlled environment. This is true because of the following:

a. Computer storage devices (like hard disks, diskettes, tapes, CD- ROMs, and DVDs) can store the equivalent of hundreds of thousands of pages of information. Additionally, a suspect may try to conceal criminal evidence, and might store criminal evidence in random order or with deceptive file names or deceptive file extensions. This requires searching authorities to examine all the stored data to determine which particular files are evidence or instrumentalities of crime. This sorting process can take weeks or months, depending on the volume of data stored, and it would be impractical to attempt this kind of data search on site.

b. Searching computer systems for criminal evidence is a highly technical process, requiring expert skill and a properly controlled environment. The vast array of computer hardware and software

available requires even computer experts to specialize in some systems and applications, so it is difficult to know before a search which expert is qualified to analyze the system and its data. In any event, data search protocols are exacting scientific procedures designed to protect the integrity of the evidence and to recover even "hidden," erased, compressed, password-protected, or encrypted files. Since computer evidence is extremely vulnerable to inadvertent or intentional modification or destruction (both from external sources and from destructive codes imbedded in the system, such as "booby traps"), a controlled environment is essential to its complete and accurate analysis.

7. Based upon your affiant's consultation with experts in computer searches, data retrieval from computers and related media, and consultations with other agents who have been involved in the search of computers and retrieval of data from computer

systems, your affiant knows that searching computerized information for evidence or instrumentalities of crime commonly requires agents to seize all of a computer system's input/output (I/O) peripheral devices, related software, documentation, and data security devices (including passwords) so that a qualified computer expert can accurately retrieve the system's data in a laboratory or other controlled environment. This is true because of the following:

a. The peripheral devices which allow users to enter or retrieve data from the storage devices vary widely in their compatibility with other hardware and software. Many system storage devices require particular I/O devices in order to read the data on the system. It is important the analyst be able to properly re-configure the system as it now operates in order to accurately retrieve the evidence contained therein. In addition, the analyst needs the relevant system software (operating systems, interfaces, and hardware drivers) and any applications software, which may have been used to create the data (whether stored on hard drives or on external media), as well as all related instruction manuals or other documentation and data security devices. If the analyst determines that the I/O devices, software, documentation, and data security devices are not necessary to retrieve and preserve the data after inspection, the government will

return them within a reasonable time.

b. In order to fully retrieve data from a computer system, the analyst also needs all magnetic storage devices as well as the central processing unit (CPU). Further, the analyst again needs all the system software (operating systems or interfaces, and hardware drivers) and any applications software that may have been used to create the data (whether stored on hard drives or on external media) for proper data retrieval.

What the Application and Affidavit for Search Warrant Is

An Application and Affidavit for Search Warrant is a sworn statement presented to a judge or magistrate requesting judicial authorization to search specified places or seize specific property. The document sets out the factual basis supporting probable cause, identifies the person(s) affected, describes the items or premises to be searched, and requests the judge sign a warrant. It typically includes the applicant's identity, the affiant's oath, a detailed factual narrative, and a proposed warrant form for judicial signature. Proper preparation is essential to preserve admissibility and avoid suppression motions.

Why a Thorough, Compliant Application Matters

A complete, well-drafted application protects constitutional rights, supports a judge’s finding of probable cause, and reduces the risk of later challenges such as motions to suppress evidence. Accuracy and clear factual linkage between allegations and requested scope are required by Fourth Amendment jurisprudence and local court rules.

Why a Thorough, Compliant Application Matters

Who Prepares and Uses This Form

Defense counsel, civil litigants, and records custodians later consult the application when assessing admissibility, chain-of-custody issues, or for discovery purposes.

  • Arresting investigators and detectives who gather facts and draft the probable cause narrative.
  • Prosecutors or district attorneys who review legal sufficiency and present the application to the court.
  • Magistrates or judges who evaluate the affidavit, determine probable cause, and sign the warrant.

Essential Parts of a Professional Application and Affidavit

A reliable affidavit organizes the legal and factual elements clearly to help the judicial officer find probable cause without ambiguity.

Caption

Case caption and court identification must match the jurisdiction and charging authority, ensuring correct judicial routing and filing.

Affiant Information

Name, badge or agency identifier, rank, and contact information so the affiant is clearly identified and accountable for statements made under oath.

Oath and Jurat

Signed oath or affirmation before the magistrate with jurat language; includes date, time, and judicial officer identification to record the sworn act.

Probable Cause Narrative

Concise factual narrative linking observations, witness statements, surveillance, or records to the items sought and explaining why each supports probable cause.

Particularity

Specific description of the place to be searched and items to be seized; avoid overly broad language to comply with the Fourth Amendment particularity requirement.

Proposed Warrant

Draft warrant language attached for judicial signature including execution directions, return instructions, and any time-limited restrictions.

Step-by-Step: Drafting and Submitting the Affidavit

Follow a clear, documented sequence from evidence collection to judicial submission to minimize procedural defects.

  • 01
    Gather Evidence: Assemble witness statements, reports, and records supporting probable cause.
  • 02
    Draft Affidavit: Write a factual narrative tying evidence to the items and locations requested.
  • 03
    Legal Review: Have prosecutor or agency counsel review for sufficiency and legal compliance.
  • 04
    Present to Magistrate: Appear before the judge or use authorized e-filing/RON procedures for oath and signature.

Configuring an Online Workflow for Applications and Affidavits

When automating preparation, map document stages to reviewers and evidence attachments to ensure auditable control.

Field Configuration
Drafting Template Prepopulate agency headers, jurat language, and signature blocks to reduce manual errors.
Attachment Handling Allow PDF attachments, numbered exhibits, and clear labeling for each supporting item.
Reviewer Routing Route to prosecutor or supervising officer before presentation to the magistrate.
Audit Trail Enable timestamps, user IDs, and version history for each edit and signature.

Where to File and How the Submission Flows

File with the appropriate judicial officer or clerk following local rules; some jurisdictions permit electronic submission or remote notarization.

  • Local Magistrate: Most applications are presented to a local magistrate or judge within the court’s territorial jurisdiction.
  • Court Clerk: Clerk’s office accepts or records the filed affidavit and issues a docket number.
  • E-Filing Options: Where available, use authorized e-filing systems to submit pleadings and attachments securely.
  • Remote Notarization: Some states accept RON for jurats if identity-proofing and audio-video recording requirements are met.

Digital Signing and eSubmission Considerations

Integrations with case management, secure storage, and e-filing systems reduce re-keying and create a clear chain of custody for court presentations.

  • Authentication: Use multi-factor or strong identity checks for signer attribution.
  • Audit Trail: Record IP, timestamp, and user actions for each signing event.
  • File Formats: Use PDF/A or PDF with embedded signatures to maintain integrity.

Timing and Processing Expectations

Timelines depend on local court procedures; some steps are immediate, others require prompt return filings after execution.

Application Submission:

Submit to magistrate as soon as probable cause is documented; local rules determine in-person or e-filed presentation.

Warrant Issuance:

Judge may sign immediately or request clarifying information before issuance; timing varies by caseload.

Execution Window:

Execution is typically prompt; judges may set a time-limited execution period or require daytime service per order.

Return Filing:

Return and inventory of seized items must be filed per court rule; some courts require filing within days of execution.

Record Retention:

Maintain originals and returns under agency record rules and any statutory retention obligations.

Common Preparation Mistakes to Avoid

  • Overbroad descriptions that request unlimited categories instead of narrowly tailored items tied to probable cause.
  • Missing or inconsistent dates and timestamps that undermine the affidavit’s chronology and factual reliability.
  • Failure to identify the affiant clearly, including badge number or agency, making attribution and accountability unclear.
  • Omitting key supporting exhibits or failing to number and label attachments that corroborate the narrative.

Consequences of an Inadequate or Incorrect Affidavit

Suppression Motion: Evidence may be excluded for Fourth Amendment defects.
Civil Liability: Bad-faith searches can lead to Section 1983 claims and damages.
Ethical Sanctions: Prosecutors or officers risk disciplinary review for intentional misstatements.
Case Delays: Improper warrants can delay investigations and prosecutions.
Return Rejection: Clerks or judges may refuse defective filings, requiring re-submission.
Local Rule Noncompliance: Violations of court procedures may complicate admissibility and enforcement.
