When Clay Ferguson was jumped in a New York City coffee shop, his attackers stole his phone, his ID and his money. Then, they broke his glasses.

Two weeks later, Clay is still jittery, blinking frantically as he looks anywhere but at me. As he recounts the night, he visibly winces at the sting of the memory.

"Horrible," the 23-year-old whispers. "It's been horrible."

Alongside the trauma are the logistics: replacing his valuables and getting new glasses. It would be a tough situation for anyone, but the process is even more complicated for Clay.

Clay is homeless.
