Why do you feel the need to include the title "soldier"? That is meaningless, the fact that he was a soldier has nothing to do with this murder. Moreover, yes he may have suffered a traumatic experience, but that has not been proven to be linked to the murder. So it is silly to speculate that the two incidents were related. Until that happens, he should be treated as a murderer, but still have a full psychiatric test to find out whether the two incidences are related. It is meaningless at this point in time to make everyone aware he is a soldier, his job is not a factor at all.
