In September, the MSU Department of Anthropology offered their four-day, Human Remains Excavation Course for Michigan State Police officers and laboratory personnel.
“This training is important for us to expand our skillset and provide the best and highest quality response for the community,” Christina Rasmussen said. She works for the Michigan State Police in the Lansing Forensic Lab and was one of 17 participants in the training.
This training provides an overview of how forensic anthropology can contribute to investigating deaths, and the appropriate methods investigators should follow when they are searching for and recovering actual human remains (although the skeletons used for training are made of plastic).
“This training is important, as service to the community is a pillar of our practice,” Dr. Carolyn Isaac said. She is an assistant professor in the Department of Anthropology in the College of Social Science, and the director of the MSU Forensic Anthropology Laboratory (MSUFAL). She collaborated with Anthropology Associate Professor Joe Hefner, PhD., on the training, in addition to receiving help from graduate students including Rhian Dunn, Micayla Spiros, Clara Devota, and Holly Long.
“We often partner with law enforcement to aid in the search and recovery of human remains and it is essential that we all understand the appropriate techniques to ensure all of the skeletal remains and evidence at the scene are collected. We also want to create relationships with our law enforcement colleagues so they know they can call us to assist in such recoveries.”
The training includes a combination of lectures and hands-on experience. Lectures feature topics such as how to assess sex, age, ancestry, and stature from skeletal remains; identifications using comparative radiography, skeletal trauma analysis; and forensic archaeology.
The department also provides a hands-on osteology (bone) laboratory so participants can try to identify the various features of the biological profile in the skeletal remains.
One afternoon is dedicated to forensic entomology (how the study of insects can contribute to the death investigation) and a field demonstration of decomposition and the collection of insects of interest. Ryan Kimbirauskas, PhD, a board-certified forensic entomologist and MSU faculty in the Center for Integrative Studies in General Science hosted this part of the training.
“On the third day (excavation day) teams search for, systematically excavate, recover, and document simulated clandestine burials (plastic skeletons that we buried back in May),” Dr. Isaac said. “From this exercise, they prepare presentations on their excavations and present them on the last day.”

On excavation day, participants are divided into a number of teams to perform line searches and probing to detect where the simulated clandestine burials are located. Once the burial locations have been determined, they begin the systematic excavation, ensuring thorough mapping and photography of the process are completed.
“The goal is to expose the skeleton to understand the position of the remains and any associated evidence when they were placed into the ground,” Dr. Isaac explained. “During this process they learn how to detect clandestine graves or soil disturbances, utilize soil probes to determine the outline of the burial, set up a grid over the burial for mapping, carefully remove soil from above the remains to ensure they are not disturbed, screen soil to find any small portions of bones or evidence, pedestal the bones (i.e. removing enough soil to expose the bones but not too much where they will fall out of place), and how to take coordinates of the skeletal remains to produce a map for documentation purposes.”
For Rasmussen, one key takeaway was the need to approach each scene differently but collaboratively.
“I learned the importance of being creative and innovative since each scene is different,” she said. “Working together as a team is the only way to effectively process a scene.”
The Human Remains Excavation course has a rich and long history that spans several decades. The training course was established by Dr. Norm Sauer, founder of the MSU Forensic Anthropology Laboratory, back in the 1990s, and it continued when Dr. Todd Fenton took over the directorship of the lab in 2012.
“The MSUFAL relationship with the MSP has been around for a long time and represents years of working together on complex forensic recoveries, death investigations ranging from suspicious deaths to multiple homicides, and everything in between,” Dr. Hefner said. “We are fortunate to have such a strong bond with the state law enforcement, and these courses provide us an opportunity to give back to the community outside of our normal academic duties.” To learn more about the MSU Forensic Anthropology Lab, visit anthropology.msu.edu.
