During the construction of what was to be an office building in Seoul, South Korea, owner Lee Joon decided to change course and make it a department store. Contractors who would not comply with his design modifications, which included removing some support columns in favor of escalators, were replaced. By April 1995, cracks were visible in the five-story structure. Two months later, in a span of only 20 seconds, the building collapsed with more than 1,500 people inside. How many of them died?
