I agree, my first impression was that Shanequa was holding something, presumably a phone, up to her ear at the Marta. And yes, she did look like she was hanging about for someone or something. I just don't understand enough about phones and apps to know what could have been happening with her phone :thinking: (too old!). I wondered if perhaps she had got talking with someone who took the Marta at the same times and was waiting to see if they showed up to help her? Or some people pretend to be on the phone, I have heard, if they feel a bit unsafe?
With regard to the clothes, it was an unusual way to phrase things. My immediate thought was that Shanequa was found in something that was very much a contrast to what she had last been seen in. Perhaps sort of party, glamorous, more dressed up than her work outfit. It seemed to be one of those things LE want to keep back in order to trip up any suspects. It could fit in with what I suspect happened, ie that someone she knew or had a slight acquaintance coerced her into doing certain things, which Shanequa then protested at and then her abductor became violent. I wish that wasn't the scenario but sadly for a vulnerable young woman, I think it's the most obvious motive to harm her.
The loss of the video is a big error on the part of the initial investigators, if there was much initial investigation which I'm not convinced of. But at the very least they could have called the airport and told them to retain the footage from that day. Even if the police couldn't be bothered to review it, Shanequa's employer has a duty of care towards her and as soon as they knew she was missing probably from their premises, they should have made efforts to get statements from colleagues (just as a workplace incident) and retained their footage. ESPECIALLY as Shanequa was a disabled employee, they should have had measures in place to give her extra help if and when she needed it.
