I'm a freckly redheaded and blue-eyed Hispanic from northern New Mexico (a couple of hours north of Abq); I was more of a strawberry blonde when I was younger. It's not that unusual. Northern New Mexico had a lot of early settlers from Spain, and some Basque (there is some evidence of genetic ties between Basques and Celts), and many Spaniards are light-haired, light-eyed, and light-complected, so it's in the gene pool. My mother and grandparents were dark-haired and dark-eyed, but I got whatever recessive genes were lurking in there from my red-headed great-grandmother who came over from Spain. There's a reason the nickname "Güerita" gets thrown around in Latin families a lot. When I was growing up, I used to hound my mother about whether or not she was my "real" mother because I thought dark eyes and hair always had to be dominant over light eyes and hair, but now that I'm older, it's obvious that my face shape and structure, eye shape, everything looks exactly like every woman in my family. Just not in coloring.
There's actually quite a bit of identity politics wrapped up in the issue of being called/calling yourself Hispanic vs. Chicana vs. Latina. And some argue that those with a genetic background from Spain should be considered European rather than Hispanic. Some of the same issues in South America, where there's a history of Spanish colonization and lighter "ruling" classes historically, vs. the indigenous population, and a huge influx of Europeans during both world wars. Look at Christina Aguilera and Shakira. Yeah, they both dye their hair, but they're also both very fair-skinned. And both are considered (and self-identify) as Hispanic, even though both have one non-Hispanic parent. So the category of Hispanic is fairly fluid.
All of that is far more than you wanted to know, of course, and beyond the scope of this particular case. My point is just not to let lighter eyes or skin or hair be an automatic rule-out for missing/unidentified persons categorized as Hispanic (unless they're specifically said to have dark eyes and hair, of course).
