Who Stole the Beach?

Ok, when I saw this news story I had to do a double take. Police in Jamaica are investigating into who stole 500 truck loads of sand form a planned resort in Coral Springs. Right now no one is sure who could have done this but by the shear amount of sand taken it seams to have something to do with the hotel industry. Apparently, illegal sand mining is a big problem in Jamaica because having a good beach is considered a valuable asset for hotels. What I would like to know is how could anyone steal 500 truck loads of sand without anybody realizing what's going on? This might have something to do with it:

"There is some suspicion that some police were in collusion with the movers of the sand."
