The rest of the story?

Here is a jumping off point for a YA novel if I ever heard one.
Read and listen to the story at NPR.

...one night last month, as Diaz stepped off the No. 6 train and onto a nearly empty platform, his evening took an unexpected turn.

He was walking toward the stairs when a teenage boy approached and pulled out a knife.

"He wants my money, so I just gave him my wallet and told him, 'Here you go,'" Diaz says.

As the teen began to walk away, Diaz told him, "Hey, wait a minute. You forgot something. If you're going to be robbing people for the rest of the night, you might as well take my coat to keep you warm."
