As someone who works with Bank Secrecy Act officers and researches various fraud/scam situations- I have grave concerns.
OP:
How well do you know this person?
Have you physically met this person?
Who is this lawyer? Has the lawyer been providing you docuмentation of some sort?
How does the lawyer want the monies delivered?
If I were a third party becoming acquainted with this story for the first time I would probably react in much the same way. That being said, I have been interacting with the people involved (Edith, her friend Sila, her brother and more recently her lawyer) in an organic way for several months and their behaviour and mannerisms do not match those of swindlers. This is even more obvious to me now that the majority of funds needed to pay the fine have been raised, not by gullible Westerners, but by Kenyans living in Kenya who know Edith personally, mostly friends of hers from university. I am working with the eminently trustworthy human rights lawyer mentioned in OP to investigate further; in the unlikely event that some kind of giga-scam is afoot, it will come to light in short order and GoFundMe's donor protection policies will come into play.
Charitable donations are never without risk; nonetheless, as someone who has been so invested in this situation the past couple weeks as to lose sleep and fail to meet deadlines at work over it, I genuinely believe that this is a case of a grave injustice that has fallen through the cracks and is worth considerable efforts to remedy.
