Are there steps/procedure in attempting to retrieve stolen items from barracks?

While on leave an NCO cut the tape on the door to my barracks room, allowing another soldier into the room. That soldier lived in my room for a little over a week while I was on leave. Upon my return, several personal items were missing, boxes & bags had been gone through and trash on the floor. Some of which have family/sentimental value and cannot be replaced or compensated for. My leadership says I can press charges on the NCO who illegally cut the tape on my door. As a private trying to grow successfully in my career, I am very uncomfortable pressing charges on an NCO. Are there other steps I can take to track down the soldier who was put into my room and attempt to retrieve my items? Or maybe a department that provides assistance with something like this?
