Gwangju: The last missing worker in a tragic library construction site accident was found dead Saturday, raising the total death toll to four in the collapse incident that happened two days earlier. The body of the 58-year-old worker, identified by his surname Kim, was discovered at around 11:20 a.m., officials reported.

According to Yonhap News Agency, the discovery of Kim's body followed the earlier recovery of another worker's body, surnamed Ko, found at approximately 1:03 a.m. on the same day. Two additional workers lost their lives on Thursday when the accident initially occurred. All four victims, identified as technicians with a subcontractor, were confirmed to be Korean nationals.

Officials suspect the collapse began as concrete was being poured onto the rooftop of the two-story structure, causing the ground floors to fall to the underground level. The library was under construction by the Gwangju metropolitan government on the site of a former waste incineration plant, approximately 300 kilometers south of Seoul.

In response to the accident, police and labor authorities conducted a raid on the headquarters of the project's main contractor to seize documents related to the construction, aiming to verify whether the necessary safety measures had been implemented. "We will thoroughly investigate the structural causes of this accident that caused multiple casualties and hold those responsible to account," stated an official at the Gwangju branch of the Ministry of Employment and Labor.

Land Minister Kim Yun-duk announced Friday that the government plans to introduce a special law to enhance construction workplace safety and impose stricter penalties for fatal accidents. This move is in response to the increasing number of such incidents at construction sites. Since taking office in June, President Lee Jae Myung has emphasized the need for stronger measures to prevent industrial accidents, following a series of incidents at sites managed by major construction companies.
