"He pointed to the fact that web developers translated the SherriPapini.com website and the ransom letter into Spanish."
I did not know this. Why would they think they had to translate it into Spanish? Did they translate it into other languages such as Vietnamese or Ukrainian?
California is a little over 40% Hispanic/Latino. You may not live in a place that has a large percentage of residence non-English speaking, but in Central Texas (with fewer than 40% hispanic) everything is translated. Letters home from the school are english on one side, spanish on the other. Food in Walmart is translated - you could learn the language just by looking at your food labels. On a chicken package, muslos are thighs, BTW. Vote Aqui. No me olvides on a picture of a reusable shopping bag. Don't even try to get through the lumber section of Home Depot without a basic knowledge of spanish.
What is your best guess as to why it was translated into Spanish in the state of California, and not, say, Ukranian?
