Another concern
The Reg article links to a couple of local news articles for more information. For some reason, the police were concerned that DeCampos might attempt to make contact with the women whose photos he had stolen. They found that he had looked up directions to at least one of the women's residences. This is just a guess on my part, but the fact that DeCampos possessed a web cam in his apartment suggests that he might have it used it while making contact with women through social networking sites and/or online messenger services. Only one of the women interviewed by police recognized DeCampos (she had seen him at BestBuy and she said his facial expression had "freaked her out"), so apparently he never made contact with any of them, but the campus police advised all the women who were living on campus to get new rooms. They seemed to be concerned that DeCampos might retaliate against them, which I admit does not make sense to me. I don't know whether DeCampos would ever try to make contact with those women, but the police had reason to believe he would.
