I always felt uneasy about the mother but didn't say anything because she was a victim. At first I thought it was strange that whenever she was on camera she had taken care with her make-up and even took time to put on her false eyelashes -- that was shallow and judgmental of me, and I would probably be critical of someone else thinking the same thing.
What really made me think that she might have something to hide was when she was so outraged that the FBI had taken her phone, and she felt that she was being discriminated against. Of course we know that it is routine for LE to confiscate the electronic devices of the parents of missing children, and most parents are willing to do anything that will help further the investigation.
I hope that JM will get all of the help and support she needs.
