Conclusion

You have a suspect in mind, and you have compiled the evidence against him.  A medieval trial is then held.  In the early Middle Ages, a trial by ordeal was held. In the later Middle Ages, at least in Britain, a more regular trial was held. The trial usually went like this.
-         The accused party is led forth before a judge appointed by the King.
-         The crimes of which the accused is charged are read out in the court, as well as the evidence against him. 
-         The accused is then given a chance to speak out on his own behalf. 
-         There is no assumption of innocence until the accused is proven guilty rather, if there seems to be more evidence against the accused than for him, he is found guilty. 
-         In many cases, it is the word of the accuser against the word of the accused, with the court deciding who is more honest and believable.
-         If the accused is found guilty, he is punished.  Punishments were swift and often harsh.
