Understanding Gun Crime Charges in O’Fallon

Legal Strategies for Challenging Firearm Allegations

Firearm charges in O’Fallon often result from traffic stops near Highway 50 or incidents reported around O’Fallon Family Sports Park. A solid defense starts by questioning how the weapon was discovered.

If law enforcement searched your vehicle or property without a valid warrant or probable cause, your attorney can move to suppress the evidence. In some cases, it may also be possible to argue that the firearm belonged to someone else, especially in shared spaces. The prosecution’s case should be scrutinized from every angle.
