I think a random choice. KK. Once the cover-up started, they couldn't stop and the more confusion they could add to scene, all the better for them! It worked, didn't it, KK? They were never arrested! I wonder if there was a metal door leading to the garage in the Ramsey basement. No dents would show if this was how the brush was broken, KK.. I'm sure the house was renovated before the Ramseys moved in. Our house is now 37 years old, and I was quite amazed to see the front door was a steel door with another door in front with a screen. So Patsy may have changed the entrance door to the garage or had a steel door at the front (?). I'm sure we have all seen most of the TV programs showing the inside of the Ramsey home, but you wouldn't know at a glance if a door was wooden or steel, not unless the host of one of the TV shows mentions it.
