Abstract

The goal of this study is to present observers with information of different forms of decomposition. We created a case where decomposition of two domestic pig heads will be observed over a 21-day period in freshwater and above ground in a wooded area in Yamhill County, Oregon. One head was placed outside in a 10-gallon aquarium with water from the Willamette River. The other freshly killed pig head was placed above ground in a live animal cage trap to keep animals from moving the carcass. We anticipate the carcass above ground will decompose at a faster rate because insects have easier access to colonize and the temperature of the exposed carcass will be higher. This research can be used to understand factors about decomposition in different environments ultimately helping estimate time since death.
