TWC NEWS VIDEO: It’s summer break for college students. A time to see friends, maybe make a little money. But one place you probably wouldn't expect a college student to be spending part of their summer is visiting a children's hospital. But that's exactly where we found RIT grad student Kayla Wheeler. To understand why, we have to go back. When Kayla was in elementary school, she became friends with a younger boy at her taekwondo school, but as Kayla and her family got closer to Nick Cammarata and his family, tragedy would soon get in the middle. Barry Wygel has the story in this Future Leaders feature.
