Legal Question in Criminal Law in Missouri

The rules of evidence are tricky. But, based upon the bare bones information you provided, it sounds like the mention of other alleged crimes was rong. If you or your attorney did not object at nthe time, it may be too late to do anything about it. It's sad, but too many people think they are saving money by not hiring counsel, but pay even more by not knowing how to represent themself. In those cases, the prosecutoir seems to have a much wider range of information they can present to get a conviction.

Good luck
