The John Wayne Gacy Activity uses a real-life case as the backdrop for identifying skeletal remains by age determination factors.
John Wayne Gacy was an American serial killer who was caught in December of 1978 when he confessed to killing over 25 young men and burying them in his crawlspace. Pre-DNA, identification of the skeletal remains was difficult as Gacy had buried many of the bodies on top of each other, intermingling the skeletal remains.
Students will use age determination factors (humerus length to calculate height, pubic symphysis, third molar eruption, humerus & radius fusion to calculate an age range) to identify the 25 known skeletons and then research the NAMUS missing person system to locate possible victims for the 8 unknown skeletons.
