If NM is anything like our state, there's a registry for all companies that are incorporated in that state, and that corporation papers would include the corporation officers and other basic information. In our case, it's the Secretary of State. It may be different in other states. But if a corp. was operating in New Mexico or using NM as its HQ, there's a very good chance that incorporation papers of some sort would be on file with some state agency. That'd be the place to start for sleuths. Of course, a number of corps are incorporated in Delaware. That'd be the second most logical place to look.
