If this sort of thing is going on in a storage facility, I find it highly improbable that the owners of the facilities have no knowledge. In fact, I would find it more likely that they are either actively in on it, or receiving a monetary kickback to turn a blind eye. If LE was there, they heard noises but did not follow up "just in case", that raises deeper questions. Whether it be a human, a cat, or a rat, a full on raid of the place is in order, complete with bloodhounds and cadaver dogs. What will it take to get every single unit inspected? If anyone at any time was living in any unit, even if they clear it out and stage legit stuff in there (or rearrange it so it appears unused), real investigative efforts would reveal that. What is the freakin' delay and what can people who reside no where near there do something to spark interest and action? Nancy Grace?
