Body farm

A body farm is a research facility where decomposition can be studied in a variety of settings. The aim is to gain a better understanding of the decomposition process, permitting the development of techniques for extracting information (such as the timing and circumstances of death) from human remains. Body farm research is particularly forensic anthropology and related disciplines, and has applications in the fields of law enforcement and forensic science. Six such facilities exist in the United States, with the research facility operated by Texas State University at Freeman Ranch being the largest at seven acres. The first body farm outside the United States is being established by the University of Technology, Sydney, with construction beginning in 2015. Facilities in the United States- University of Tennessee at Knoxville: The original "Body Farm" is the University of Tennessee Anthropological Research Facility located a few miles from downtown on Alcoa Highway in Knoxville, Tennessee, behind the University of Tennessee Medical Center . It was first started in late 1981 byanthropologist Dr. William M. Bass as a facility for the study of the decomposition of human remains. Dr. Bass became head of the university's anthropology department in 1971, and as official state forensic anthropologist for Tennessee he was frequently consulted in police cases involving decomposed human remains. Since no facilities existed that specifically studied decomposition, in 1981 he opened the department's first body farm. It consists of a 2.5-acre (10,000 m2) wooded plot, surrounded by a razor wire fence. At any one time there will be a number of bodies placed in different settings throughout the facility and left to decompose. The bodies are exposed in a number of ways in order to provide insights into decomposition under varying conditions. observations and records of the decomposition process are kept, including the sequence and speed of decomposition and the effects of insect activity. Over 100 bodies are donated to the facility every year. Some individuals pre-register before their death, and others are donated by their families or by a medical examiner. 60% of donations are made by family members of individuals who were not pre-registered with the facility. Over 1300 people have chosen to pre-register themselves. Perhaps the most famous person to donate his body for study was the anthropologist Grover Krantz, as described by his colleague David Hunt at the Smithsonian. The University of Tennessee Body Farm is also used in the training of law enforcement officers in scene-of-crime skills and techniques. Western Carolina University: The second human decomposition facility to open in the United States is located at Western Carolina University in Cullowhee, North Carolina and is part of the Western Carolina Human Identification Laboratory. The facility is known as the Forensic Osteology Research Station or more commonly as the FOREST. It was opened in 2006 and is run by WCU's Forensic Anthropology program on a small plot on the rural mountain campus. The facility studies decomposition in the western North Carolina mountain habitat and has been used for cadaver dog training. Texas State University: A Forensic Anthropology Research Facility was commissioned by the Texas State University-San Marcos Department of Anthropology and is under the direction of Dr. Michelle Hamilton, a former student of Dr. Bill Bass. The forensic research facility is fully operational and is part of the Forensic Anthropology Center at Texas State (FACTS). The forensic facility has received a financial donation of over $100,000 from a Distinguished Professor Emeritus of Texas State University, and has started construction of an adjoining million dollar lab to augment the facility. The development of this facility has been possible through the efforts of Dr. Jerry Melbye, D-ABFA. Prior to the selection of the location, objections by local residents and the nearby San Marcos Municipal Airport (owing to concerns about circling vultures) stalled the plan. But on February 12, 2008, Texas State University announced that its Freeman Ranch, off County Road 213 northwest of San Marcos, would be the site of the facility. The vultures that originally created problems for the location of the research facility have provided a new area of study on the effect of vulture scavenging on human decomposition. A new body is brought to the facility every five or six months. The sources of the bodies typically consist of Texas hospitals, funeral homes, or medical examiners' offices; from there, they are strapped to a gurney, loaded into cargo vans, and brought to the ranch, where researchers and student volunteers begin their research on the corpses. The Forensic Anthropology Research Facility (FARF) is a human decomposition research laboratory where questions related to outdoor crime scenes and decomposition rates for human remains under various topographical and climate conditions are investigated. The FARF serves as a resource for students of forensic anthropology as well as state and national law enforcement agencies. The work conducted here will have a direct impact on law enforcement and forensic investigations throughout the state of Texas, and beyond. The Forensic Anthropology Center at Texas State accepts body donations for scientific research purposes under the Uniform Anatomical Gift Act. The areas of research conducted with donated bodies will include reconstructing the postmortem interval to determine time since death and related studies in human decomposition. The overall aim of this type of research is to assist law enforcement agents and the medico-legal community in their investigations. While practical restraints currently limit the Forensic Anthropology Research Facility to only around seven acres in the Texas Hill Country, Freeman Ranch has about 4,200 acres (17 km2) available. Freeman Ranch is a working ranch that also serves as an educational model for ranch management. It is an area of land for educational outreach and research. Researchers and students visit the ranch and participate in educational activities and projects. Researchers and students are allowed to conduct experiments and studies at the ranch, including forensic anthropology. Sam Houston State University: The Southeast Texas Applied Forensic Science Facility (STAFS) is a state-of-the-art research and training facility designed to advance academic and technical knowledge in the application of forensic science disciplines to crime scenes and criminal activities. The facility's predominant focus of study is the application of forensic sciences to the human body and the vast amount of evidence that can be gleaned from the careful recognition, collection, and preservation of that evidence. The facility is recognized by the Anatomical Board of Texas as a willed-body donor facility, and accepts human body donations for the purposes of scientific research. The facility trains students, law enforcement officials, academicians and forensic specialists. The facility is located within the Center for Biological Field Studies at Sam Houston State University, a 247-acre (100 ha) parcel of land adjacent to the Sam Houston National Forest. One acre of maximum security fencing surrounds the outdoor research facility with an additional 8 acres (32,000 m2) of minimum security reserved for other types of forensic training such as search and recovery maneuvers. Contained within the outdoor facility are a variety of various environmental conditions, including a fluvial environment. Web cams are located within the outdoor facility to monitor timing of various post-mortem activities from on and off-campus computers. The building is designed as a morgue with cooler and freezer units, modern morgue equipment and tools and digital radiograph and microscope capabilities. The environment in southeast Texas is quite different from the environment of East Tennessee. East Tennessee's mean annual temperature is 67 °F (19 °C). The Huntsville, TX area's mean annual temperature is 75 °F (23 °C). Temperature, along with many other factors, affect the decomposition process, and therefore difference in temperature will produce different decomposition results. Southern Illinois University: The Complex for Forensic Anthropology Research (CFAR) opened at Southern Illinois University (Carbondale, IL) in October 2010 working with pigs as human proxies. The co-founders, Gretchen R. Dabbs and D.C. Martin, built the facility to examine the rate and pattern of decomposition in the unique environment of southern Illinois. In comparison to the other facilities open at the time, CFAR has the lowest average temperature, highest average wind speed, second lowest elevation, the most acidic soil, and the worst soil drainage. Since climate and environment are major factors affecting the rate and pattern of decomposition, these differences between southern Illinois and the other established facilities were expected (and have proven) to heavily influence the rate and pattern of decomposition. The first human donation was accepted at CFAR in January 2012. CFAR is a unit within the Department of Anthropology (College of Liberal Arts) at SIU. It is approximately 0.33 acres of grassland surrounded by privacy fencing with razor wire. Outdoor cameras are used to monitor access for security purposes and record research events. Current research focuses on establishing the baseline rate and pattern of decomposition in the unique southern Illinois environment. Additionally, researchers at CFAR attempt to mimic clandestine body disposal situations and understand how the process of decomposition is altered by those postmortem treatments and how the postmortem treatment can be identified after skeletonization. The faculty and staff of CFAR also participate in forensic anthropology consultations and provide training seminars for local, state, and federal law enforcement agencies. Colorado Mesa University: The Forensic Investigation Research Station (FIRS) opened as part of Colorado Mesa University in Grand Junction (www.coloradomesa.edu) and is under the direction of Dr. Melissa Connor. Its location outside of Whitewater Colorado provides, compared to the other facilities open at the time, the highest altitude (4750' AMSL) and the most arid (averaging 8" of rain a year) environment. FIRS consists of both indoor and outdoor research facilities. The outdoor facility is about an acre of fenced area surrounded by privacy fencing with razor wire. Outdoor cameras are used both for security and research. The indoor facility consists of a classroom, wet lab/ morgue, walk-in cooler, in-take area, office, and secure storage areas. The first pig was placed in the outdoor facility Sept 2012, the indoor facility opened for classes in January 2013, and the first human donation was placed in November, 2013. Most remains desiccate quickly and current research focuses on the variation in the desiccation process and determining the post-mortem interval on mummified or desiccated remains. The focus at FIRS is on education and students include Colorado Mesa students, as well as practitioners, law enforcement, coroners, coroner deputies, and forensic scientists.
