Whoever took the pictures is the owner of them and their copyrights and can do what they like with them, subject to the rights of the people in the photos, who have privacy and publicity rights.
Privacy rights include the right to not have your image put in a "false light," so that the image misrepresents you in some way.
Publicity rights, if your state has such laws, gives people and thewir licensees the exclusive right to exploit their own images for profit.

Your statement that someone had "turned [the pictures] in to show proof" suggests that they were submitted as part of a court proceeding. If so, then it may be considered fair use under copyright law. The Copyright Office provides a more detailed discussion of fair use at http://www.copyright.gov/fls/fl102.html.

It sounds to me like you're in the service [I spent some time with the Big Red One myself], you have Facebook page, and someone's out gunning for you.
If that someone accessed your Facebook page then he or she was only able to do so because your settings are such that you allowed access. So the person very likely did not violate Facebook's terms of service agreement.
It is unlawful, however, to right click and copy photographs if you do not own the copyright in the photographs. There are exceptions but none that come to mind in the situation that you describe. In short, if the person who right clicked and copied the photographs was not the person who actually took the photographs ["took" in the sense of using a camera to capture your image] then that copying is very likely unlawful.
But there's unlawful and then there's unlawful. If I was your CO I would not want to hear your gripe about copyright infringement in response to whatever you allegedly did wrong. There's just too much to do in a unit. My suggestion is to stand tall and move on.
