Study of Biological Samples Obtained from Victims of MGM Grand Hotel Fire

Abstract

Eighty blood samples and 17 respiratory-tract tissue samples containing fluid taken from victims of the MGM Grand Hotel fire were studied to assist in the determination of the cause of death. The blood and tissue-fluid samples were analyzed for carboxyhemoglobin, oxyhemoglobin, methemoglobin, and total hemoglobin. Outgassing studies were done on the tissue samples using gas chromatography/mass spectroscopy, and heavy metal analysis on inhaled soot was done by x-ray fluorescence. The carboxyhemoglobin values obtained on the samples were significantly higher than those reported by Clark County. However, the percentage of the victims with a carboxyhemoglobin saturation level of 50% or less is higher than that found in the Maryland fire fatality study, suggesting that other toxic factors may have contributed to the lethal nature of the fire.
