In the aftermath of the tragedy, it was determined that a number of factors served as potential causes, including wood in the building that was more than 50 years old, coupled with thermostats often kept at to keep residents comfortable during the frigid winter months. The facility had been inspected just one week earlier by a state official. However, in the immediate aftermath of the tragedy,
arson was suggested by one
Missouri State Police officer when it was disclosed that the sister of the Home's manager had run a similar facility in
Hillsboro, Missouri in which 18 people died in a 1952 fire. During the subsequent investigation, the notion of arson was dismissed as the final determination was that the blaze started from an undetermined cause. Despite this finding, the facility had been operating without a license, had inadequate fire escapes, and lacked a sprinkler system. In addition, there was no alarm system nor evacuation plan, while some residents were locked in their rooms, being a common practice of that period. The end result of those omissions came when Missouri Governor
James T. Blair signed a bill in March 1957 that established minimum safety standards for nursing homes in the state. ==References==
