Hi Spunky.This is a quote from your post.
"They don't say if the call originated from Amber's phone or Scott's phone or what time this call was made. If the call originated from Amber's phone, I wonder if they are positive Amber talked with Scott or maybe Laci picked up the phone and then got into a confrontation with Scott."

There are three sources that it was Amber who called Scott the Dec 23rd.The first is Greta VanSusteren speaking to Howard Breuer.Here is the conversation from the transcript.
Van Susteren: All right. Howard,Dec 23,a phone call from Amber Frey,the girlfriend. Can you tell us the details?
Breuer: Well,we don't know the details of the call. There's speculation that that might have set off a heavy argument between Scott and Laci....
The second source is from Catherine Crier,and it was posted on court TV. A reported call had been placed from Amber the night before Christmas Eve to Laci and Scott's house.
The third source is an article from the CBS affiliate Channel 5. It was posted on their website,the pix page,titled,New Information About scott Peterson's Affair,which goes on to say,"Channel 5 reports that on Dec 23,Frey called the Peterson home and Laci reportly answered the phone".

IIRC, Amber's father vehemently denied on national TV that Amber ever spoke to Laci.

Good work, Maggie! Makes it pretty clear.

"There are three sources that it was Amber who called Scott the Dec 23rd."

Wow! Are these quotes recent? After this article came out on all the calls made or were they from way back when Amber's father denied that she had ever called Laci?

I have so many questions I would like to know the answer to.

1. If Amber thought Scott was going to be in England or France, (or wherever it was) over Christmas, like was said in some articles, why would she call him on his cell phone on Christmas Eve? Do cell phones go across continents?

2. To my knowledge it has never been said whether or not Amber knew Scott lived in Modesto but I find it hard to believe she didn't know. I have never had a cell phone, but wouldn't their number indicate a local like a regular phone's area code?

Since I believe she knew where he lived and she has a sister living in Modesto, I think she had her sister check him out.
