and then, whats his name from CSI Miami takes off his glasses slowly and nods in the direction of a dumpster over in the corner of the south Florida parking lot his team is collecting evidence at...

I think I've just found the source...

And he sees a man's legs hanging out of the dumpster which is next to a new black Lexus

Now why would a man driving a car like this go in there, and for what?

they pull the body out and the dead man's hand is clutching a movie theater cup with a torn AA miles coupon on it... The coupon is gone and there's a bullet hole in his head
