The intruder IMO, was either:
- Really stupid/desperate/dumb and lucky all at the same time.
- OR -
Someone who knew:
- Dad was working late, really late that night.
- That mom and boys were sleeping.
- Mom would have the older boy, and not the baby in her bed.
- That mom would close all the bedroom doors at night.
- Which door was the door to the baby's room.
- The three cell phones were the only phones in the house.
- Baby Lisa would not cry or fight being taken out of her crib.
- They would not be seen entering or exiting.
- The dog, and neighbor's dogs wouldn't bark at them.
Oh, and also -
The person was also an expert at breaking and entering into occupied homes.
They left no fingerprints, hairs, or DNA at the scene.
