Did a little searching on line and found this in an article by Steve Lopez (from page 2 of the online version):
"Everything he had told me about his life was checking out, so I figured Juilliard must be for real too.
Sure enough.
Nathaniel Anthony Ayers, who sleeps on the streets of the city, takes his meals at the Midnight Mission and plays a two-string violin, attended the acclaimed New York City music school on a scholarship.
Nathaniel told me a bass player named Homer Mensch was one of his mentors at Juilliard. Mensch, 91, is still teaching, and he immediately recalled Nathaniel.
"He had the talent, that was for sure," said Mensch, who remembered that Nathaniel had suddenly disappeared, never to return. I told him Nathaniel's illness had begun while he was at Juilliard and he was now a homeless violinist in downtown L.A.
"Give him my very best," said Mensch. "I would certainly like to hear from him." "
