Ivy, Alberto didn't go to the front door, but to the "front doors" (american for "french windows": access from the garden to the kitchen...). Defence even asked Alberto why didn't he go to the front door as William had asked him.
my understanding he went to the front door
Alvarez Testimony
Q: okay. And what, if anything, did Michael Amir Williams tell you at that time?
A: he proceeded to ask me if I was at the property. I said yes. He said, "okay, please, get up. don't be so abrupt. But, you know, go to the front of the house." he said, "walk to the front. Don't run." once I was walked --
Q: okay. So can you show the path you took from the trailer to the front door?
A: I went out from this door here, and I start from the door from the trailer. And then I came down this way. There is a driveway, and I continued to go into the front door.
Q okay. For the record, you have indicated you came out -- as you look at people's 1, you came out again as looking at the photo, you came out of the right side of the trailer, walked along the exterior of the house along the driveway to
what is depicted as the front of the house to the front door?
A: a that's correct, sir.
Q okay. And while you are walking this path, are you on the telephone with Michael Amir Williams?
A: Yes, I am.
Q: and are you continuing to converse with him?
A: yes. And he continued to say, "okay, never mind. Jog to the front of the house." so I started hurrying a little to the front of the house.
Q: okay. And did
you actually go to the front door in an attempt to open the door?
A: Yes, sir, that's correct.
Q: okay. And
were you able to gain access to the door immediately?
A:
not immediately. The door was locked.
Q: showing you people's 2 for identification, sir, do you recognize that as a closeup of the front door area?
A: a yes, sir.
Q: okay. And zooming in to the front door, are those,
does that accurately reflect glass doors that you can see through?
A: a yes, sir.
Q: okay. And were you looking through those doors at the time you approached the front doors?
A: when I noticed that it was locked, I proceeded to look and focus inward.
Q: and when you first looked in those glass doors, what, if anything, did you see?
A:
I saw the nanny.and I saw Paris next to her. and I also saw Kai Chase further down. and then I looked toward the top, and I noticed Mr. Conrad Murray.
now look to his description
Q can you describe the general vantage point and what we are looking at in
people's 6?
A: Yes.
It's the main entrance to Mr.Jackson's home. To the left, you had your stairwell, a top balcony. And then to the bottom right, you would have a walkway to the kitchen, to the further right down the hallway.
Q: okay. Now if I heard you correctly, when you looked in the front door, one of the people you saw was Michael Jackson's daughter Paris?
A: yes, standing right next to Rose, Rosalind.
Q : okay. And is that general area where you saw Rosalind and Paris, is that general area depicted in people's 6?
Q : okay. For the record, as
you are looking at people's 6, it would be to the left of the photo near the chair and the stairway access to go upstairs? And that was where both sister Rose and Paris was located?
A: that is correct.
Q: where was Kai Chase located if it's depicted in people's 6?
For the record, you are pointing to people's 6.
she would be further back from Paris and Rosalind on the right side as you look at the photo?
Q okay. And is that -- where you were pointing to, if you were to walk into the home proceeding straight forward as depicted in people's 6 and proceeded
to the rear, would the kitchen be to your right?
A : that is correct, sir.
Q : okay. Now you also indicated you saw Doctor Murray; is that right?
A: yes, sir.
Q: and where did you see him as you looked in through the glass of the front door?
For the record,
you are pointing to the top most portion of people's 6 which is showing the wood railing of the landing area?
A: a yes, sir.
----------------
As you can see Amir Williams told him to go to the front doors and that's where he went. Kitchen doors would have been on the right back.
People's 6 is the main entrance area. When Alvarez comes to the front door and looks through the windows he sees Paris and the nanny by the foot of the stairway, Chase right back towards the kitchen and Murray on the stairway.
so by his description he was looking through the main front doors and not the kitchen doors.
------------------------
and here are some photos
front entrance front glass doors
stairwell
and what Alvarez was looking at
as this photo was taken from the inside it shows the stairwell on the right. when Alvarez looked to it from outside it would be on the left. and you can see the chair they mention when describing where Paris and the nanny was.
and I believe this is an view that shows both main and side enterances as well as the security trailer. (Poort is the main street entrance from Carolwood dr. You can see the side entrance at Monovale drive - which looks like at the right back side of the house where the kitchen is reported to be. and my guess the white thing is the security trailer)
