Ok my student has written "in the incriminated evening" (she meant the evening of the crime) - the full sentence is "She looked quite nervous during her visit to his shop in the incriminated evening." Now I know "incriminated evening" makes no sense - my question is in the "in" and "on". I'm almost certain it should be "on the evening of the crime" or "on the evening in question" - first, am I correct? (and is there a better way of saying "night of the crime"?) Secondly, please someone explain or give me a link to explaining the difference between "in the evening" and "on the night of the murder" - I know the difference but for the life of me I don't know how to explain it. That one is general, some time in the evening and the other's specific?
