U.S. Students Among Those Killed in Seoul Crowd Surge

The father of a U.S. student killed in the Halloween crowd surge in South Korea is speaking out. His son, Steven Blesi, was a 20-year-old Georgia college student in a study abroad program in South Korea. Before the tragedy, he texted his son, "I know you're out and about. be safe." Hours later, he learned Steven was one of 154 people crushed to death in the disaster in Seoul's nightclub district.
