That is what I was thinking, in the party pictures their hair color is very similiar, but in these pictures the tall girl in pic 1 has much lighter hair than the young girl in pics 2 and3. Maybe its just a lighting thing.
That's true, plus her hair is pulled back, making it harder to see, and the pictures look like they may have yellowed a little bit.
Trying to figure this out, I looked up an article I remember reading a few weeks ago. In it Jaycee's step-grandmother says that she was told that Garrido would take the girls out to eat and to SF sometimes, but that Jaycee was never taken along.
Here is the link.
Like another poster said, I have wondered who was taking the pictures and if it was Jaycee.
