改变历史的罪案：杀人小丑

立功手法层出不穷，破案手法也一日千里。法医人类学和鉴证学自降生以来，更是随着科技的提高不时展开，仅仅依托骨头就能在最严酷的凶杀案中发扬关键作用。约翰·韦恩·盖西是一名美国连环杀手和强奸犯。他在1972年和1978年之间，对至少33名年龄由14岁至21岁的男孩及年轻男性中止了性侵犯和谋杀。盖西先后将26名受益者埋在他家的供电管道空间，3名埋在他房产的其他中央，并将最后4名已知的受益者的遗体丢弃在左近的河里。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.
