Facing Arson Charges in Wyoming: What the Law Says and What Is at Stake
Arson charges in Wyoming are pursued aggressively by prosecutors — particularly when the fire involved an occupied structure or resulted in injury. Fire investigations are conducted by specialized state fire marshal investigators and sometimes involve federal agencies. By the time charges are filed, the prosecution typically has an expert-supported case. You need experienced legal representation from the moment charges are filed.
Wyoming’s Arson Statute and Charge Levels
Under Wyo. Stat. § 6-3-101, arson involves intentionally starting a fire or causing an explosion that damages a building or structure. Wyoming distinguishes between arson in the first degree — involving occupied structures or fires set with intent to defraud an insurer — and arson in lower degrees involving unoccupied structures. The degree of the charge determines the severity of the penalty.
Penalties for Arson in Wyoming
First degree arson in Wyoming is a felony carrying up to 20 years in state prison. Second degree arson carries up to 14 years. Even lower-level arson charges carry significant prison exposure. When arson results in injury or death, additional felony charges — including aggravated assault or homicide — are likely to follow. Insurance fraud charges frequently accompany arson investigations where a financial motive is alleged.
How Arson Cases Are Investigated and How We Challenge Them
Fire cause and origin investigations are a specialized science — and they are not infallible. The prosecution’s fire investigator will testify about how the fire started and whether it was intentional. We work with our own fire cause and origin experts to challenge the prosecution’s conclusions. Many arson cases rely heavily on expert opinion, and competing expert testimony has led to acquittals and dismissals in these cases. We also examine whether the financial motive the prosecution alleges is actually supported by the evidence.
