Mario González Contreras doesn’t like speaking at universities.
The students who fill the lecture halls and seminar rooms are about the same age as his son, César. He notices his son’s features in their faces. Or maybe, he looks for them. And that’s when it hits him the hardest.
On Sunday evening, González stood behind a lectern at Saint Louis University’s Center for Global Citizenship. About two dozen students listened intently as he talked about his son.
