Felony offenses are categorized under Missouri Revised Statutes Chapter 558, which establishes the sentencing ranges and classifications for felony crimes. Specifically, RSMo § 558.011 divides felony offenses into different classes that determine the possible penalties a defendant may face following a conviction.
In O’Fallon, MO, felony prosecutions frequently involve allegations such as:
- Drug trafficking and distribution offenses
