I'm sure it was just a case of bad luck and not any targeting thru the internet. If this was a highly mod'ed truck, maybe. Water World isn't in the nicest part of town and I'm sure thieves just troll thru the lot looking for something easy that they know they can get a few bucks for, your 4Runner fit the bill. Trucks like this are obviously popular to steal though because 1, they're easy to take, no modern anti-theft technology and 2, there is a large demand for them as well as demand for parts they could strip them for.
Any help from Water World security, parking lot camera footage, etc.? What did the cops say? Sucks all around and reminds me I need to add some anti-theft measures to my son's 4Runner before I give it back to him after all the work I'm doing to it.
