I appreciate the support, however I am positive this person is not this person. A quick twitter search can show that she, Jessy is not this person. Sorry to disappoint :)
I do however ask that you respect the Privacy of those who agreed to be painted.
As for your concern about the person vanishing, they are fine and healthy. They have been since before the date of you posting that. They were asking people to stop spreading the flyer info by earlier that month.
I can't help but to of looked into what you mentioned, as I do worry about people, even complete strangers! Stay safe out there. :)
