What Happens In A Federal Criminal Case?

Federal prosecutions follow a set path that includes:

Investigation: Often secret, sometimes before an arrest
Arrest/indictment: Formal charges are filed
Arraignment: You plead guilty or not guilty
Pretrial: Discovery, motions and plea discussions
Trial: If no resolution is reached, your case goes before a judge and jury
Sentencing: If convicted, your sentence is imposed
Appeal/post-conviction: If needed, we also handle appeals

We prepare every case as if it is going to trial – because that is what gets results, even during negotiations.
