Really not sure why race and skin color is such a debate.
Kat stated correctly, Latinos may or may not classify or self- identify as white/Caucasian. Some identify as AfroCaribbean, some as indigenous, some as mixed race, some as Caucasian.
If I robbed a bank, I would be described as a "Caucasian female". If they put out my description, my close friends might write me off as a possible suspect because they will think, "she's not white, she's Latina". And that is what IMO they are trying to avoid with this case. The person has light skin. If they are light skinned, fit the rest if the description, don't NOT CALL because of whatever race they are.
