I have 2 points to make:
1. Everyone is making a big deal of no one came or left by the front door all day. We don't have videos of "all day", so who knows. A large number of people I know never use their front doors, they enter by the side, some into mud rooms, others into family room, etc. (A friend whom I had known for over 20 years had a bridal shower and opened her front door - it was the first time I had seen it open! It felt strange.)
2. The nephew is NOT Andrea Peck's son. His family name is Cierzan and she is his aunt. I am too tired to go look, but it clearly says so near the beginning of this thread. It also gave his first name and Facebook account. From Facebook, and I will be as nice as I can, lets just say that he doesn't look like the type who would go watch golf with his middle age uncle. If I saw him somewhere, I would walk faster....
