Father of U.S. boy killed in Sri Lanka: Terrorists don't know what they took

The father of an 11-year-old boy, who was among at least 4 Americans killed in Sri Lanka's attacks remembered his son as a "self-driven" world traveler, who was learning 3 languages, in an interview with KTNV-TV Monday.

What he's saying: "The terrorists didn’t know who they were killing. But we should know what the world lost," Kieran Shafritz de Zoysa's father, Alex Arrow, said. "A brilliant mind who, who was going to be a neuroscientist and... he won’t make it to his 12th birthday. ... They just blew themselves up, they have no idea. ... His story should be told."
