Just realized I never followed up on this post.
I am happy to say that he, Matthew, is safe and sound and finally home.
It took us a while to find him and get him out, but our friend was relentless in his search for him and was finally able to get him released.
He is doing great and has settled in just fine. When we asked him to join us, he told the uncle he never thought he was going to get off the streets. I am so happy that he is finally home with us and I can introduce you to our newest addition.
