Mystery Bird Found Dead in Texas--Alcid?

A reader sent me this link to the Victoria Advocate in Texas about a weird bird found dead on the side of the road. At first the people who found it thought that the dead bird was a penguin but after consulting with people at Texas Parks and Wildlife Department it was decided that it might be a loon. I think it's some kind of alcid, but then again I am a land locked Minnesotan with not a lot of experience with seabirds. Any guesses from you guys? Any Texas birders read the blog, have there been any discussions about a mystery bird on the side of the road?
