While in the process of moving from one apartment complex to another on my college campus (The College of New Jersey), they unlocked all the doors which has resulted in several of my items still in the room going missing. Also, unlocking all the doors and when exactly residents had to have their stuff moved out because this was going to be happening was something residents were never notified of.
The College of NJ is a state institution. There are limits on what can be received absent gross negligence.
You should have the equivalent of renter's insurance to cover theft and damage, but you can file a claim with the university, and IF an attorney is willing to handle what I perceive as a rather small claim, you may get the attorney to handle it on a contingency fee face.
Alternatively, although not highly recommended, you can file a claim with the Superior Court, Civil Division, Small Claims Part in the county seat where the College is located and see if a settlement can be reached. Having pictures or proof of purchase of the items lost/stolen will help your case as you carry the burden of proving you even owned the property you allege was stolen. Roommates be helpful if willing to appear on your behalf.
By all means file a police report with both campus security and the municipal police if you have not done so already.
The foregoing is not intended to be legal advice upon which you may rely as I have not been retained for this purpose.
