First of all...I have holdon on my ignore list...so you posters out there....please alert me if he answers this question. I have asked many question...but he can not or will not answer them. So, I will break them down for him (or her).
Okay...sooooo....intruders break into the Ramsey's home while they were at the Christmas party...right?? And waited for the Ramsey's to return.

So how did the intruders know how long the Ramsey's were going to be gone? How did they know that they were going to have enough time to write that RN? How did they know that the Ramsey's weren't out grocery shopping...or maybe John had gone to get gas, and Patsy was in the shower...or Burke and JB were at a friends house and would be back ANY minute?? How did the intruder...

...know that the Ramsey's wouldn't just walk in on them at any second...while they were writing that two and a half page RN?? How did they know that NOBODY was home? If they saw the car leave...and it was dark...(it gets dark around 4 o'clock in Colorado...in Dec. I lived in MT...two states up)...then how did they KNOW who was inside the car? How did they know that a relative of the Ramsey's wasn't STILL inside the home? Or the housekeeper?? OR A DOG??? How did they know that the Ramsey's had a burgular alarm...but, by george...it didn't work, because it had been disconnected?? How did they know that when they were looking for a flashlight...

...that the Ramsey's wouldn't suddenly appear from upstairs....or come back from getting gas?? How did they KNOW how much time they had.....to be able to move so freely around in the house? Looking for JB's size 12 panties...the flashlight...the pen....the paper. Going upstairs to look around and find JB's bedroom...so that they would know where to go to kidnap her.

I mean...the Ramsey's could be back at any time...ANY TIME! And again..thats a big, old house....somebody could have still been there...in the shower, for example. My question is....in case you didn't get it.....is HOW DID THEY KNOW???
