Okay, just had this thought while taking a bath getting ready for work:
Sergio "says" that they all took their showers that evening. I would assume that this would include Isabel. (I would think bath, but I'm old-fashioned that way.)
Now, when the 14 year old is asked what Isabel was wearing during his 911 call, he assumes that she's wearing pyjamas, but has no details. In other words, that's what she USUALLY wears to bed.
Are you gonna tell me that she had a shower, hair braided, and gets BACK in her street clothes, so to speak? IF she had PJ's and normally wears PJ's?
What was she wearing that day? Is this the same outfit? I think that if she had been wearing PJ's, the mom would have said, she had on blue PJ's with an American flag or whatever, not that she was wearing shorts and a top, etc.
IMO, she NEVER went to bed.
(I dunno, this all seemed significant to me while I was in the bathtub!)
