犯罪手法層出不窮，破案手法也日新月異。法醫(yī)人類學和鑒證學自誕生以來，更是隨著科技的進步不斷發(fā)展，僅僅依靠骨頭就能在最殘忍的兇殺案中發(fā)揮關(guān)鍵作用。 約翰·韋恩·蓋西是一名美國連環(huán)殺手和強奸犯。他在1972年和1978年之間，對至少33名年齡由14歲至21歲的男孩及年輕男性進行了性侵犯和謀殺。蓋西先后將26名受害者埋在他家的供電管道空間，3名埋在他房產(chǎn)的其他地方，并將最后4名已知的受害者的遺體丟棄在附近的河里。 In 1978 the grisly discovery of a crudely buried collection of skeletons beneath a house in Illinois led police to one of the most notorious serial killers in US history: John Wayne Gacy aka the ‘Killer Clown’. Accused of 33 murders, Gacy was known for his appearances at charitable events and children’s parties dressed as ‘Pongo the Clown’. With a staggering number of human remains to identify, investigators turned to expert forensic anthropologist Dr. Clyde Snow for help – and in doing so, paid a debt to the ground breaking CSIs who used similar techniques to convict the murderous ‘sausage king of Chicago’ almost a hundred years earlier.
