Police raided the private hospital for chronically ill patients in South Jeolla, South Korea, where a fire killed 21 people to see if bad management contributed to the deaths, according to an article on the Korea Joongang Daily website.

South Jeolla police sent investigators to confiscate evidence from the long-term care hospital for seniors suffering from Alzheimer’s Disease, strokes and other conditions.

Police had already found that only one auxiliary nurse was on duty to care for 34 patients when the fire broke out in a storage room on the second floor of the hospital annex. 

The fire killed 20 patients and the nurse, and injured eight. Police said most of the victims died of smoke inhalation.

Among the questions police are focusing on is if the hospital had a proper fire protection system and whether some doors in the building were locked when the fire broke out.
