I overlooked where it said it had been two months, as the post above states chances of a CD now are pretty low as they tend to happen within the normal shipping period and they would have attempted to make the delivery and gotten you to sign for it which is one of the most commonly used tactics. I have heard of CD's for lessor amounts, the truth is there are no hard and fast rules for determining what LE will or won't do in any given situation so you should always assume the worst case scenario. Chances are you will never find out what happened and nothing will ever happen but at the very least you should consider the address you ordered to as compromised and not order to it again. Tracking updates are also notoriously unreliable, just because it updated to delivered doesn't necessarily mean it was as it clearly wasn't delivered to you. At the very least you should consider the address as compromised, better to be safe than sorry.
