What should I do if my attorney committed suicide and my complete file is missing from the law firm?

I’ve been working with an attorney for the past year regarding a VA claim. I provided this attorney a 3in binder with a lot of medical and personal information inside. Some of this information can not be recreated or found anywhere else outside that file. I have over the past year requested by email this file be returned to me without success.
The attorney recently committed suicide and removed my entire file from the law office. His partners said they couldn’t locate my file and provided me only a paper copy of some emails, and authorization forms.
They have since told me there is nothing more they can do in locating my original private information.
Issues: I’m currently a Law Enforcement officer and if ever sued these documents may hurt my case. Nothing illegal should be noted.
There was evidence in there that would support my claim which can not get again. The doctor's office shut down and I had to sign for my entire file as well as my medic in Iraq gave me the originals of everything.
Besides filing a complaint with the Virginia Bar Association for HIPPA Violations, pricey act concerns, and professional misconduct, do I have any other options?
