It seems there are many possibilities.. such as they came in through the back where there were no neighboring cameras? Or they arrived inside H's car with her (or B's car for that matter)? Or police actually might *have* footage, but they're not announcing it and have possibly asked any neighbors to keep a lid on it if they want to see this solved? Or someone hid out in the home's basement for a couple of days waiting? It seems footage from say Monday or whatever, was not even looked at by the neighbor, I believe I read that neighbor hadn't even looked at the Wed evening?
