Criminal Law Attorney in Casper, WY: Trial Prep Guide

Admin • September 29, 2025

When facing criminal charges, working with an experienced criminal law attorney in Casper, WY can make a life-changing difference. A strong defense doesn’t begin in the courtroom, it starts long before trial with careful preparation, investigation, and a comprehensive strategy tailored to the client’s unique situation. At Chapman Valdez & Lansing, Attorneys, and Counselors at Law, our team understands the stakes. We focus on protecting rights from the very beginning while building the strongest case possible.


Steps a Criminal Law Attorney in Casper, WY Takes to Build a Strong Defense


Step 1: Gathering and Analyzing Evidence


The foundation of any defense begins with evidence collection. A defense attorney will review police reports, body cam footage, and forensic test results with a critical eye. They look for inconsistencies, missing documentation, or evidence collected in violation of constitutional rights.


In some cases, defense teams may hire independent investigators to collect additional materials such as surveillance video, cell phone data, or witness statements that law enforcement may have overlooked. A criminal law attorney in Casper, WY ensures every piece of evidence is analyzed in detail to identify weaknesses in the prosecution’s case.


Step 2: Reviewing Police Reports and Procedures

Police reports form the backbone of most prosecutions, but they are not immune to error. Officers may omit key details, misinterpret events, or fail to follow proper procedure. Your attorney will carefully examine these reports to identify areas where your rights may have been violated.


For example, if evidence was obtained during an unlawful search, it may be suppressed and deemed inadmissible in court. Similarly, if statements were taken without proper Miranda warnings, they may be excluded from trial. Identifying procedural mistakes early is essential, and it can shift the balance of the case significantly in your favor.


Step 3: Interviewing Witnesses and Experts

Witness testimony often plays a central role in both prosecution and defense. Your lawyer will interview potential witnesses to confirm the reliability of their accounts and uncover inconsistencies that may create reasonable doubt.

Expert witnesses are equally important. Forensic specialists, psychologists, or accident reconstruction professionals can provide testimony that challenges the prosecution’s narrative. By bringing in experts, your criminal law attorney in Casper, WY ensures the jury hears alternative perspectives supported by science and professional expertise.


Step 4: Examining the Crime Scene


Visiting or revisiting the alleged crime scene can reveal critical insights. A site visit may show that a witness’s account doesn’t align with physical realities such as visibility, lighting, or layout. These observations can undermine the credibility of testimony and strengthen the defense.


Crime scene analysis can also identify potential evidence missed during the initial investigation. Small details, like camera locations or environmental conditions, often make a big difference when presented effectively in court.


Step 5: Filing Pretrial Motions and Attending Hearings


Pretrial motions are powerful tools in shaping how a case proceeds. 


Common motions include:


  • Motion to suppress evidence (if collected unlawfully)
  • Motion to dismiss charges (when the prosecution lacks sufficient evidence)
  • Motion in limine (to exclude certain testimony or evidence)


Attorneys attend hearings to argue these motions and challenge the prosecution’s preparation. A successful motion can significantly reduce or even eliminate the charges before trial. These hearings also provide an early opportunity to gauge the prosecution’s case strategy and identify additional defense options.


Step 6: Negotiating With Prosecutors


Not all cases go to trial. In fact, many are resolved through plea negotiations. An experienced defense attorney knows when to pursue a plea agreement and when to push forward to trial. Skilled negotiation can result in reduced charges, lighter sentencing, or alternative resolutions such as diversion programs.


Prosecutors in Natrona County courts are familiar with repeat offenders, case patterns, and community priorities. That is why having a local criminal law attorney in Casper, WY is so important, someone who understands the tendencies of judges, prosecutors, and juries, and who can leverage that knowledge during negotiations.


Step 7: Building the Trial Strategy


If a case proceeds to trial, your attorney prepares a comprehensive defense plan.


 This includes:


  • Outlining cross-examination questions to challenge prosecution witnesses.
  • Preparing opening and closing statements designed to resonate with the jury.
  • Organizing evidence into a compelling narrative.
  • Anticipating prosecution arguments and planning counter-strategies.


Trial preparation also involves coaching clients and witnesses on courtroom demeanor and expectations, ensuring that every person involved is ready to present confidently before the judge and jury.


The Value of Local Knowledge

Each jurisdiction has unique procedures and personalities within its courts. A defense strategy that works in one county may not be as effective in another. Working with a criminal law attorney in Casper, WY ensures you have representation that understands the specific practices of local courts.


This local insight extends to jury selection, relationships with prosecutors, and familiarity with past rulings. Chapman Valdez & Lansing has deep experience in Wyoming courts, giving clients an edge in cases where nuanced knowledge of the legal system is invaluable.


How Clients Can Assist in Building a Strong Defense


The attorney-client relationship is a partnership. Clients play a critical role in building the strongest defense possible. 


You can assist your attorney by:


  • Being honest and transparent about all case details.
  • Providing documentation such as receipts, text messages, or employment records that may support your defense.
  • Staying engaged and responsive during case preparation.
  • Following legal advice closely to avoid complications.


The more proactive and cooperative you are, the better equipped your attorney will be to defend your case effectively.


Why Thorough Preparation Matters


A rushed or incomplete defense leaves clients vulnerable. By thoroughly preparing before trial, attorneys can anticipate prosecution tactics, highlight weaknesses in the case, and create a strategy designed to secure the best possible outcome.


Every step, from evidence review to pretrial motions, serves as a safeguard against unfair treatment. For clients, this preparation translates into peace of mind, knowing that their future is being defended with professionalism and dedication.
