Move-in day for students at the University of Southern California this week led to a remarkable small-world moment between two strangers with ties to the Holocaust in the public-exhibit space of USC Shoah Foundation’s lobby.

Fifty-eight-year-old Alexander Moissis of the San Francisco Bay Area and his wife were helping their freshman son move into a dormitory when Alexander decided to steal away for a few minutes to visit USC Shoah Foundation, which is located on campus next to the dorm.

Their loved ones – including women and children – were slaughtered by the military and tossed into mass graves.

For more than 30 years, survivors of the Guatemalan Genocide against the indigenous population assumed nobody cared about their stories.

After all, nobody had ever bothered to ask.
