2 U.S. College Students Killed in South Korea Crowd Crush, Families Say They're 'Devastated' and 'Heartbroken'

Two college students from the United States were killed after a Halloween celebration turned deadly in South Korea on Saturday, when at least 153 people died in a crowd surge. They have been identified by school officials and family members as Anne Gieske and Steven Blesi.

Gieske, a junior studying nursing at the University of Kentucky, was in South Korea this semester as part of a study abroad program, the school said in a statement.

"I have the incredibly sad responsibility to inform you of the loss of one of our students over the weekend," wrote school president Eli Capilouto. "The crowd apparently surged at some point into a crush of people. Details of what happened and why are still unfolding."

"There aren't adequate or appropriate words to describe the pain of a beautiful life cut short. It isn't fair, nor is it comprehensible. It is loss and it hurts in ways that are impossible to articulate," added Capilouto.

"We are completely devastated and heartbroken over the loss of Anne Marie. She was a bright light loved by all," her parents said in a statement shared by the city of Fort Mitchell, Kentucky.

Blesi, 20, was an international business major at Kennesaw State University in Georgia.

"Kennesaw State University officials were deeply saddened to learn that KSU student Steven Blesi was among the more than 150 people tragically killed in this weekend's Halloween incident," school officials wrote in a statement.

"On behalf of the entire Kennesaw State community, our thoughts and prayers go out to Steven's family and friends as they mourn this incomprehensible loss," said Kennesaw State University President Kathy Schwaig. "We have been in contact with Steven's family and have offered all available resources of the University to them."

"We are heartbroken," his father, Steve Blesi, tells PEOPLE. "The world's a darker place without him in it."

Over the weekend, the student texted to tell his dad he was going out with some friends.

"I texted him through What's App the night of this and he told me he was going to be out with friends because they had finished midterms," his father says. "I told him, "Okay, I know you're out and about, but be safe and I love you."

After learning about what had happened in Seoul, the family tried to contact their son as well as government officials, according to The New York Times. Finally, hours later, they received a call from the U.S. Embassy in South Korea.

"When they said, 'Are you sitting down?' I knew the next words that were coming outta their mouth was that our son had died," he tells PEOPLE. "I can't imagine the pain he went through."

Over the weekend, at least 153 people were killed and 103 were injured when a crowd surge occurred in a narrow alley in Itaewon, an area in Seoul, according to NBC News. A crowd surge happens when large numbers of people rush forward in the same direction.

According to the outlet, the popular nightlife spot was reportedly swarmed with 100,000 residents there to enjoy festivities at the first large Halloween gathering since the pandemic.

In a national address, South Korean President Yoon Suk-yeol called it "a disaster that should never happen," and ordered an emergency review into what happened, per NBC News.

Speaking with The Washington Post, Steve Blesi said he "never thought something like this would happen," and questioned why better crowd control measures weren't put in place by local officials.

The police "should have been better prepared," he told NBC News.
