This study collected data on specific volatile fatty acids (VFA's) produced from soft tissue decomposition and on various anions and cations liberated from soft tissue and bone deposited in soil solution under decomposing human cadavers to determine time since death.
Abstract
Seven nude subjects, including two black males, a white female, and four white males, were studied at a decay research facility during various times of the year and were allowed to decompose naturally. Data were collected every 3 days in the spring and summer and weekly in the fall and winter. Initial study results demonstrated that two variables became important determinants of the concentration of VFA's in soil solution, amount of moisture already present in soil and body weight prior to decomposition. Data revealed distinct patterns in soil solution for VFA during soft tissue decomposition and for specific anions and cations once skeletonized. Decomposition rates provided valuable information for estimating the maximum time since death. The authors hope the findings will encourage greater reliance on and awareness of the value of collecting soil from under corpses that can be used in time since death, weight, and racial determinations. 46 references, 3 tables, and 5 figures
