Statute of Limitations for Class A / 1st Degree Felony in Wyoming

Overview

In Wyoming, the statute of limitations sets a deadline for the State to file a criminal case after an alleged offense. For a Class A / 1st Degree felony, the default lookback period is 4 years—unless a statutory exception extends (or otherwise changes) the time to prosecute.

DocketMath’s statute-of-limitations calculator is built to help you translate the Wyoming rule into a concrete “earliest latest” timeline using the date of the alleged offense and, where relevant, the presence of exception-triggering facts. This page focuses on the governing Wyoming statute and the specific exception category reflected in Wyo. Stat. § 1-3-105(a)(iv)(C).

Limitation period

Default SOL period: 4 years for the Wyoming provision covering this category.

In practice, the limitation period question usually comes down to two inputs:

• Date of the alleged offense (or the relevant triggering date).
• Whether an exception applies under Wyoming law (for example, certain conduct that tolls or extends the limitations period).

How the 4-year period is commonly applied

Once you have the triggering date, the basic computation is:

• Start: the relevant offense date (or other statutory trigger tied to the charged conduct)
• End: 4 years later

DocketMath uses this structure so you can see the “deadline” date produced by the 4-year term. If the calculation flags an exception pathway, the output can shift from the default 4-year deadline to a different end date, depending on what Wyoming’s exception language provides.

What to expect when you change inputs

Even without legal advice, you can use the calculator workflow to understand how outputs change:

• Same offense date, no exception: the SOL end date stays exactly 4 years after the trigger.
• Same offense date with an exception indicator: the calculator can move the SOL end date forward to reflect the statutory extension/tolling logic for the exception category.
• Different offense date: the SOL end date moves accordingly (because the term is anchored to the trigger date).

Key exceptions

Wyoming’s limitations framework includes enumerated exceptions that alter the default 4-year analysis. For the “Class A / 1st Degree felony” category addressed here, the provided statutory mapping points to exception M1 in Wyo. Stat. § 1-3-105(a)(iv)(C).

In addition, the underlying limitations statute contains references indicating other exception groupings that correspond to the same 4-year base with different exception labels (as reflected in the jurisdiction data). These are typically handled as separate branches in a limitations analysis tool:

• Wyo. Stat. § 1-3-105(a)(iv)(C)

  • Base term: 4 years
  • Exception label in the jurisdiction data: M1
• Wyo. Stat. § 1-3-105

  • Base term: 4 years
  • Exception label in the jurisdiction data: M3
• Wyo. Stat. § 6-2-101

  • Base term: 4 years
  • Exception label in the jurisdiction data: N1

DocketMath represents these as option pathways so users can align their timeline to the governing statutory branch reflected by the charged offense and the facts that may trigger an exception.

Checklist: facts that commonly affect the outcome

Because exception triggers are fact-specific, treat this checklist as a prompt for what to verify (not as legal advice):

Statute citation

The statute-based rule identified for Wyoming’s 4-year limitations period for this category is:

• Wyo. Stat. § 1-3-105(a)(iv)(C) — 4 years — exception M1

Related statutory references (also shown in the jurisdiction data as 4-year with different exception labels) include:

• Wyo. Stat. § 1-3-105 — 4 years — exception M3
• Wyo. Stat. § 6-2-101 — 4 years — exception N1

Use the calculator

Use DocketMath’s statute-of-limitations tool at /tools/statute-of-limitations to compute the deadline date using Wyoming’s 4-year rule for this category.

You’ll typically work through the calculator by providing:

• **Offense date (trigger date)
• **Jurisdiction: Wyoming (US-WY)
• Felony category alignment (Class A / 1st Degree)
• Exception selection (if the fact pattern fits an exception branch reflected in the statute)

If you want to see it immediately, open /tools/statute-of-limitations and run the default calculation first. Then, if you have reason to believe an exception applies, rerun the calculation using the matching exception pathway.

What the output means

A typical statute-of-limitations calculator output will present:

• A computed SOL end date (based on the 4-year rule)
• An indication of whether a selected exception branch alters that deadline
• A quick “deadline window” you can compare to case filing or charging dates

To keep the result practical, match the calculated end date against the procedural milestone that matters for your timeline (often the date of charging or filing). If the relevant milestone occurs after the computed deadline, that supports a limitations argument in many systems; if it occurs before, it generally supports timeliness. However, your exact procedural posture matters.
