1. Yes, most people would. However. Since we are talking about a possible murder, normal goes out the window.
2. Yes, but we are not talking that long.
3. Go play. And stay out of my room.
4. Again, stay out of my room. And since we don't know how they died we don't know it was a horrible scene.
5. It the hustle and bustle of Christmas, get in it drive it to the mall and have someone pick you up.
But again, to even play that hypothetical, you assume they were killed during the day. They could have just been subdued until a later time.
Like when the child is shuffled off to a neighbor while oh idk, you are watching that danged car. Oh wait...
Yep . That danged car!
