Legal Question in Criminal Law in Missouri

It is possible, although unliikely to get sentenced to six months in jail for the type of harrasment misdemeanor you described. You did nto indicate the type or extent of threat, so that determination could go up or down. Since this can result in jail time and significant fines, you shoudl consult direclty with a criminal defense attorney in your area. Many offer a free or low cost initial consultation. You may not hire one to represent you, but you shoudl get advice specific to yrou case, rather than rely only on the generalized answers you can get to your generalized question here.

Good luck
