Makes alot of sense Kat, he made a point of going in to tell the boys to be quiet, because she's going to sleep. I read on here somewhere the boys left with RC from the ballpark, and Isa left with SC and I wonder where that came from. It would also make sense as to why LE was looking for her in any of the 9pm 4/20 to 10am 4/21 on the traffic cameras. Also, you can't entice a child to go with a stranger in the middle of the night. It would have to be someone she knew to get her to go out of the house, if that's where she was taken from.
I hate to go over this again, please bear with me.
A LONG time ago I suggested the family could have taken 2 cars knowing Sergio had to be there early and stay late. Rebecca had a very early morning, and might (IF THEY HAD TAKEN 2 CARS) have left as soon as the game ended. The logical thought would be that she took all three kids home to bed, or AT LEAST Isabel, since she was so young and ALSO had to be up fairly early. I speculated that IF THERE WERE TWO CARS, and Becky was headed to her car with the kids, but Isabel wanted to stay with her Dad, Becky MIGHT have relented and sent her back to the field. If this was the case, Sergio would think all three kids left with Becky. When Becky and the boys got home, they went to shower and/or play video games. Becky went to bed.
Isabel might never have made it back to Sergio, but since he would have assumed she left with Becky, he would not have even LOOKED for her. When he got home and saw Becky was asleep, he might have decided to turn on the game in the Living Room. If Isa's door was closed and there was no light shining under the door, he could have assumed she too was asleep, and not have worried until the next morning when he went to wake her. In this context, he might actually have said to Becky "get your butt home now". But my assumption is that, while he told the 911 operator this, he did NOT say it (in htose terms) to Becky.
HOWEVER, we have since heard that Becky braided Isabel's hair in the home that night, before sending her to bed. If this is true, everyone got home. And to (hopefully) end speculation, NOBODY has EVER stated FOR SURE that they did not all ride together. That was a "what-if" scenario posed long ago that still comes up occasionally.
