I would hazard a guess that this is probably the first violent crime that has occured in Aruba in many years. Aruba is hardly a third world armpit. It's a very small island, with little to no crime, and it's only industry is tourism. When I was there, they had a big sign in the middle of the town celebrating 900 and some odd days since even a fatal traffic accident had occured. The island of Aruba is very clean and neat, no serious crime at all, and probably the only crime they deal with are drunk and unruly tourists and maybe a little shoplifting. I can tick off half a dozen horrendous crimes right off the top of my head that have occured in FL just this year alone.
No, they also have refineries. This lapse causes me to question your other assertions.
