What Wyoming Law Says About Assault Charges
Assault charges in Wyoming can arise from a single moment — an argument that escalated, a confrontation that got physical, or an accusation from someone you trusted. However it happened, you are now facing a criminal charge with real consequences, and the prosecutor assigned to your case is already preparing. You need someone preparing your defense with the same urgency.
Simple Assault vs. Aggravated Assault in Wyoming
Under Wyo. Stat. § 6-2-501, simple assault occurs when a person intentionally attempts to cause bodily injury to another, or threatens to cause bodily injury and has the ability to do so. Simple assault is a misdemeanor in Wyoming, carrying up to 6 months in jail and a $750 fine. Aggravated assault — which involves serious bodily injury, a deadly weapon, or strangulation — is a felony carrying up to 10 years in prison. The line between the two charges often comes down to facts that are disputed, which is exactly where an experienced defense attorney operates.
Penalties for Assault and Aggravated Assault
A misdemeanor assault conviction in Wyoming can mean up to 6 months in county jail and fines up to $750. Aggravated assault is a felony with up to 10 years in state prison. Beyond incarceration, a conviction affects your employment, your housing options, and your ability to own firearms. If the charge involves a domestic relationship, the consequences expand further into restraining orders, child custody, and federal firearms prohibitions.
Common Defenses Against Assault Charges in Wyoming
Self-defense is one of the most frequently used defenses in Wyoming assault cases, and Wyoming law supports it. Under Wyoming’s self-defense statute, a person is justified in using force when they reasonably believe it is necessary to protect themselves from imminent unlawful physical harm. Defense of others applies the same logic to protecting a third party. Other strong defenses include lack of intent, false accusations, and mutual combat — where both parties were willing participants and the question of who is the aggressor becomes contested. We have taken assault and battery cases to Wyoming juries and won. State v. Davis — Family Violence/Battery: Not Guilty. State v. Van Horn — Battery: Not Guilty.
Why the First 48 Hours After an Assault Charge Matter
Witness memories fade. Surveillance footage gets overwritten. Text messages and social media posts get deleted. Physical evidence disappears. The first 48 hours after an arrest are when the most critical evidence is still available — and having an attorney working on your case during that window can make a significant difference in how your defense is built.
