Note that all of the phone numbers listed except the Lake County Sheriff's Office are not real phone numbers - the exchange code (the set of three digits in the middle) is invalid, and thus those numbers will never be assigned to a subscriber. The Sheriff phone number is the actual phone number for the Lake County Sheriff non-emergency line.

If you are still confused or want to confirm your theories, I have now added a set of spoilers explaining it all on the second page of the comments.
