I would think that outfit - even if in black and white - is pretty telling. They wore attire that I think is more easily identifiable then just some plain black outfit. Such as those gloves. Now they can figure out the manufacturer and maybe start looking at people who may have recently bought them along with that sweater he (clearly a man) was wearing.
TBH - I really was starting to have my doubt about this. I hope this poor woman is still with us, but I don't know.
I hope the family can get justice for her.
WHO TF does this to a frail 84 year old woman who was apparently very well-liked??
