Hmm, did the hotel cameras have audio as well as visual?
It would have been simple for any one of these web sites to call the Baltimore cops and find out if an incident report was filed. They might not say anything about the report since no charges were filed, but the last I knew, police logs were still public record. That would indicate the time of the call, the location of the call and a word or two on the incident. It also might indicate who responded to the call. Any decent reporter would try to get something out of the cops who were there, off the record at least, to confirm what the heck took place.
