Father of US student killed in Seoul Halloween crowd crush: "I feel like I have a hole in me"

U.S. student Steve Blesi was one of among the more than 150 people killed in the Halloween crowd surge in Seoul's Itaewon area.

"I feel like I have a hole in me. A big hole in my chest. It's like being in a nightmare that you can't wake up from," his father said. "I texted him...''I know you're out and about, but be safe I love you.'"
