Hand write it. Somewhere in the application process it will say a hand written letter explaining events that led to blah blah blah. Also put it on nice stationary. Second, only state facts. Do not go into great detail about this that and the other, just keep it simple and to the point. Example... On (date of incident) I was.......... Remember state only facts and not your opinion or how you felt about the situation. The BON does not care how you felt or your opinion they only want to know who, what, where, when, and why. End the letter with the outcome. What was the end result after all was said and done. Did you complete jail time, probation, community service...whatever it was let them know that you complied with any request that were asked of you. I would be able to better help you if I knew why you were having to write a letter. Either way, I hope this helps.
