Understanding Body Farms: Where Science Meets Death Investigation
What is a body farm might sound like something from a horror movie, but these facilities are actually sophisticated outdoor research laboratories where donated human remains decompose under controlled conditions to advance forensic science.
Quick Answer: What is a Body Farm?
- Definition: Outdoor research facility studying human decomposition
- Purpose: Determine time since death for criminal investigations
- Founded: 1972 by Dr. William M. Bass at University of Tennessee
- Current Count: 10 body farms worldwide (8 in the United States)
- Research Focus: Post-mortem interval, forensic entomology, skeletal identification
- Body Sources: Voluntary donors, medical examiner cases, family donations
Seven miles northwest of San Marcos, Texas, "50 or so naked human bodies in varying stages of decomposition are strewn about in a 16-acre field." This isn't a crime scene—it's the Freeman Ranch body farm, where scientists study taphonomy (what happens to bodies after death) to help solve murders and identify unknown remains.
The first body farm opened in 1972 when Dr. William M. Bass established the Anthropology Research Facility at the University of Tennessee. These facilities place donated bodies in various conditions—buried in shallow graves, submerged in water, left in vehicle trunks, or exposed to different climates—to understand how environmental factors affect decomposition rates. The data helps forensic investigators estimate post-mortem intervals and verify suspect alibis in homicide cases.
As we at American Mortuary Coolers have experience in mortuary refrigeration systems, we've worked closely with facilities that require precise temperature control for body preservation, which gives us unique insight into what is a body farm and how these research sites complement traditional mortuary practices.
What Is a Body Farm? Definition, History & Founding
What is a body farm? The answer takes us back to a spring day in 1972 when forensic anthropologist Dr. William M. Bass faced a puzzling case at the University of Tennessee, Knoxville. He'd been called to examine what appeared to be recent remains in a Civil War-era grave, only to find they belonged to a Confederate colonel who had died over a century earlier. The pristine preservation shocked Bass—and highlighted a glaring gap in forensic science.
Bass realized that investigators were flying blind when it came to human decomposition. They relied on animal studies and guesswork to estimate time since death, which could make or break criminal cases. This revelation led Bass to establish the world's first body farm—the Anthropology Research Facility at UT Knoxville.
The first donated body arrived in 1981—a 73-year-old man who had died of heart disease. Within two weeks, researchers documented how the skull became bare bone and the abdomen collapsed. These weren't gruesome observations but crucial scientific data that would help solve future crimes.
What is a body farm in scientific terms? It's a controlled outdoor research facility where forensic anthropologists study taphonomy—the process of what happens to bodies after death. The primary mission is understanding decomposition to help criminal investigators determine post-mortem intervals and improve identification of human remains.
What Is a Body Farm in Modern Forensics?
Today's body farms have evolved far beyond Bass's original vision. Modern facilities are sophisticated research laboratories that study the necrobiome—the complex ecosystem of microbes, insects, and scavengers that drive decomposition.
What is a body farm accomplishing for forensic science today? These facilities use cutting-edge technology including DNA sequencing, machine learning, and environmental monitoring to create predictive models for decomposition rates. Temperature and climate play huge roles—bodies decompose much faster in hot, humid conditions than in cold, dry environments. Soil chemistry matters too, as different soil types can either accelerate decay or help preserve remains.
The research has grown incredibly sophisticated. Instead of basic questions like "When do blowflies arrive?" scientists now study microbial succession patterns that could provide a "microbial clock" for estimating time since death within days rather than weeks.
Why the Term "Body Farm" Captivates the Public
The phrase "body farm" captures public imagination in a way that "Anthropology Research Facility" never could. Patricia Cornwell's bestselling novel "The Body Farm" brought widespread attention to the University of Tennessee facility, though the actual research is far more methodical than sensational. What is a body farm in popular culture versus reality? Media portrayals often focus on the shocking visual of bodies scattered across a field, but the day-to-day work involves careful scientific observation and data collection.
The fascination also stems from our complicated relationship with death. Body farms represent a unique intersection where scientific necessity meets cultural taboo—human remains serving the living by advancing forensic knowledge that helps solve crimes and identify unknown victims.
How Body Farms Advance Forensic Science
When detectives find human remains, three critical questions determine whether they can solve the case: How long has this person been dead? Who is this person? And what evidence can we recover from the scene? Body farms provide the scientific foundation to answer all three questions with unprecedented accuracy.
Post-mortem interval estimation has transformed from educated guesswork to precise science. Traditional forensic entomology tracks insect life cycles—blowflies typically arrive within minutes of death, laying eggs that develop through predictable maggot stages. But what happens when there are no insects? Winter conditions, sealed containers, or indoor environments often lack the insect activity that forensic investigators have relied on for decades.
Enter the necrobiome—the fascinating world of microbes that colonize bodies after death. Researchers have found that bacterial communities change in predictable patterns, creating a "microbial clock" that works even when insects don't. University of Tennessee scientists can now estimate time since death within 2-3 days during early decomposition stages, a breakthrough that's revolutionizing criminal investigations.
The skeletal collections built from body farm research represent the largest treasure trove of forensic identification data ever assembled. The University of Tennessee houses over 1,800 individuals in their Donated Skeletal Collection—the biggest contemporary human skeletal database in America. This incredible resource allows forensic anthropologists to determine age, sex, ancestry, and height from bone measurements using sophisticated software like FORDISC.
Evidence recovery training transforms theoretical knowledge into practical skills. The FBI Evidence Recovery Team has trained at Tennessee's facility for over 20 years, learning proper excavation techniques and crime scene processing. Cadaver dog teams practice locating buried remains, while investigators learn to use ground-penetrating radar and other technologies to find clandestine graves without destroying crucial evidence.
Notable Findings & Breakthroughs
Body farm research has produced game-changing findings that directly impact how investigators solve crimes. Vulture scavenging rates research at Texas State University revealed that these birds arrive within minutes and can completely strip remains in just hours. This finding helps investigators understand bone scattering patterns around crime scenes.
The microbial clock breakthrough came through the Human Postmortem Microbiome project, funded with an $843,000 grant. Scientists identified specific bacterial communities that change predictably after death, potentially narrowing post-mortem interval estimates from weeks to days.
FORDISC software development emerged from the Forensic Data Bank containing information on over 4,080 forensic cases. This program helps forensic anthropologists determine demographic characteristics from bone measurements, turning fragments of skeletons into identifiable individuals who can finally be returned to their families.
The Forensic Anthropology Center continues pushing the boundaries of forensic science through ongoing research. As one researcher powerfully stated, "I think the worst thing that anyone can face is not knowing what happened to their loved one." This work provides answers that bring closure to grieving families while ensuring justice for victims.

Where Are Body Farms Located? A Global Map
When people ask what is a body farm, they often wonder where these unique research facilities actually exist. As of 2023, ten body farms operate worldwide, with eight scattered across the United States and two international facilities pushing the boundaries of decomposition research.
The geographic spread isn't random—it's strategic. Scientists need to understand how different climates affect human decomposition, from the sweltering heat of Texas to the mountain chill of North Carolina. This climate diversity helps forensic investigators make accurate time-since-death estimates no matter where a crime occurs.
The Tennessee pioneer started it all in 1972 when the University of Tennessee, Knoxville established the original 2-acre facility. Today, this founding body farm processes over 100 donated bodies annually, with more than 1,300 people already pre-registered as future donors.
Western Carolina University brought body farm research to the mountains in 2006. Located at 2,271 feet elevation, this facility studies how cooler, mountainous terrain affects decomposition while involving undergraduates in 95% of research activities.
Texas State University's Freeman Ranch claims the title of world's largest body farm at 26 acres. Since 2008, this facility has studied decomposition in hot, arid Texas climate, typically holding about 50 bodies at once. The extreme heat creates different decomposition patterns than cooler climates.
Sam Houston State University operates a unique setup with a 1-acre maximum-security facility plus 8 acres for training exercises. Since 2012, they've focused heavily on law enforcement education and clandestine grave detection.
The Southern Illinois University facility studies Midwest climate conditions with particular emphasis on soil chemistry. Colorado Mesa University researches decomposition at high altitude in arid conditions, where dry heat can actually induce mummification rather than typical decay.
University of South Florida's USF-FORT facility represents the newest frontier in climate research. Since 2017, they've studied decomposition in subtropical environments, where heat and humidity create dramatically different decay patterns. George Mason University rounded out the U.S. facilities in 2021.
Beyond American borders, Australia's AFTER facility at the University of Technology Sydney opened in 2016, focusing on bushfire victim identification. Canada's REST[ES] facility in Quebec fills a critical gap by studying decomposition in cold-weather conditions.
Several countries are planning their own facilities. Proposals exist for body farms in the United Kingdom, Netherlands, and India, though some face regulatory or cultural challenges.
Here in Tennessee, where American Mortuary Coolers is based, we've seen how the original body farm has advanced forensic science. The climate diversity across all these facilities helps investigators understand that a body found in Florida's humidity will decompose completely differently than one found in Colorado's dry mountains—knowledge that can make or break a criminal investigation.
Ethics, Donation & Community Concerns
When people first learn what is a body farm, they often have mixed reactions—fascination about the science mixed with concerns about how these facilities operate. These are valid questions that deserve thoughtful answers, especially since body farms handle one of humanity's most sensitive subjects: death and human remains.
Informed Consent and Donor Requirements:
Every body farm operates under strict ethical guidelines that put donor consent first. The body donation process requires careful documentation and clear communication with families during difficult times.
Most donations come from two sources: about 60-70% from families making decisions after a loved one's death, and 30-40% from people who pre-registered as donors. The University of Tennessee facility alone receives over 100 bodies annually, with more than 1,300 people already signed up as future donors.
But not everyone can donate. Facilities have medical exclusions for safety reasons—bodies with infectious diseases like HIV, hepatitis, or antibiotic-resistant bacteria can't be accepted. There are also practical limits on weight (typically 250-500 pounds) for volunteer safety, and since COVID-19, facilities now require negative tests even after death.
Community Relations and Concerns:
Having a body farm move into your neighborhood isn't like getting a new coffee shop. Communities often push back initially, and their concerns are understandable. During planning phases, local residents have protested with signs reading "This makes us SICK," worried about everything from property values to groundwater contamination.
The biggest worries usually center on odor issues during hot weather, insect attraction (blowflies arrive within minutes), and scavenger activity from vultures and coyotes drawn to the site.
Facilities work hard to address these concerns through privacy fencing, controlled access, and environmental monitoring. They also invest time in community education, helping neighbors understand how this research helps solve murders and identify unknown remains. Most communities eventually come around once they see the real forensic value of the work.
Biohazard Safety and Protocols:
Body farms aren't casual outdoor labs—they operate as Level 2 biohazard laboratories with serious safety protocols. Anyone working with remains must wear full personal protective equipment: coveralls, gloves, booties, and arm cuffs. The facilities maintain secure perimeters with cameras, patrols, and controlled access.
This isn't just about protecting researchers—it's about respecting donor privacy and keeping the public safe. As companies like ours at American Mortuary Coolers know from working with mortuary facilities, proper safety protocols are essential when handling human remains in any context.
Cultural Sensitivity:
Perhaps the most delicate aspect of what is a body farm involves navigating cultural and religious feelings about death. As one anthropologist put it, "There is no culture on Earth that leaves a body without any ritual." Body farms must balance scientific necessity with deep cultural values around how we treat the dead.
The key is emphasizing that donors are making a meaningful contribution to science—helping solve crimes, identifying unknown remains, and bringing closure to grieving families. Facilities treat all donors and families with "utmost respect and compassion," ensuring the research serves both scientific advancement and humanitarian goals.

Studying, Training & Who Can Access a Body Farm
Body farms aren't just research facilities—they're active classrooms where the next generation of forensic scientists learn to solve crimes and identify unknown remains. These outdoor laboratories serve multiple educational purposes, from training graduate students to teaching FBI agents proper excavation techniques.
Graduate and Undergraduate Programs
Most body farm research involves graduate students working toward degrees in forensic anthropology, biology, or related fields. The competition is fierce—the University of Tennessee program receives about 60 doctoral applications annually but accepts fewer than 10 students. These lucky few get hands-on experience that can't be replicated in traditional classrooms.
Western Carolina University takes a unique approach by involving undergraduates in 95% of their research activities. Students participate in everything from donor intake to skeletal processing, gaining practical skills in excavation techniques, bone identification, and evidence documentation.
The University of Tennessee's forensic anthropology program has educated about 25% of all board-certified forensic anthropologists in the United States as of 2007. When you consider what is a body farm accomplishing for education, these facilities are literally training the experts who solve tomorrow's criminal cases.
Law Enforcement Training
Body farms provide specialized training that no classroom can match. The FBI Evidence Recovery Team has trained at the Tennessee facility for over 20 years, learning skills that directly improve their ability to process crime scenes and locate buried remains.
Law enforcement officers learn clandestine grave detection using ground-penetrating radar and electromagnetic induction equipment. They practice proper excavation techniques that preserve evidence context while recovering remains. The training also covers cadaver dog instruction, teaching detection dogs to locate human remains under various conditions.
NCIS personnel and officers from agencies like the Tennessee Bureau of Investigation and Kentucky Criminalistic Academy regularly attend these programs. The hands-on experience with actual human remains provides training that mannequins or animal proxies simply can't replicate.
Interdisciplinary Research Opportunities
Modern body farm research brings together experts from multiple fields, creating unique collaboration opportunities. Geologists study how decomposition changes soil chemistry. Archaeologists apply excavation techniques to forensic contexts. Entomologists track insect succession patterns for time-since-death estimates.
The microbiology aspect has become particularly exciting, with researchers analyzing bacterial communities in the necrobiome to develop more accurate post-mortem interval estimates. Engineers work on developing better detection technologies for buried remains.
Volunteer and Access Requirements
Getting access to body farm research isn't easy, but opportunities do exist for dedicated students. Western Carolina University receives about 80 volunteer applications per semester but selects only 20-40 students. The selection process considers academic background, physical and emotional readiness, and commitment to maintaining donor confidentiality.
Volunteers must complete prerequisite coursework, often including osteology or biological anthropology. They need to demonstrate they can handle working with human remains in biohazard conditions while wearing appropriate protective equipment.
Several facilities offer professional development courses for working forensic professionals. These range from public courses available to anyone over 18 to specialized training programs for international forensic experts.

Frequently Asked Questions About Body Farms
How do body farms determine time since death?
What is a body farm most useful for? Determining when someone died. These facilities use three main scientific approaches that work together like pieces of a puzzle.
Insect succession remains the most established method. Blowflies show up within minutes of death, laying eggs that hatch into maggots following predictable development cycles. Forensic entomologists can look at which insects are present and what stage they're in to estimate time since death.
But insects aren't always reliable witnesses. They might not show up in sealed containers, during winter months, or in indoor environments. That's where newer methods come in.
Microbial analysis represents the cutting edge of body farm research. Scientists study the "necrobiome"—the bacterial communities that change predictably after death. This research has achieved accuracy within 2-3 days during early decomposition stages. The beauty of this "microbial clock" is that it works even when insects aren't present.
Soil chemistry provides another piece of the puzzle. Decomposing bodies release fluids that alter soil acidity and chemistry in measurable ways. Researchers analyze soil samples around remains to detect these changes and estimate how long decomposition has been occurring.
Environmental factors tie everything together. Temperature, humidity, sun exposure, and scavenger activity all affect decomposition rates dramatically. Body farms study these variables across different climates so investigators can adjust their estimates based on whether remains were found in hot Texas desert or cold Michigan winter.
Can anyone donate their body to a body farm?
Body donation isn't as simple as checking a box on your driver's license, but it's more accessible than many people think. The process requires meeting specific health and logistical requirements.
Most donations actually come from families making decisions after a loved one's death—about 60-70% according to facility data. The remaining 30-40% are from people who pre-registered as donors. The University of Tennessee has over 1,300 people pre-registered, showing strong public support for this type of research.
Health requirements exist mainly for researcher safety. Facilities cannot accept remains from individuals who died of infectious diseases like HIV, hepatitis, or antibiotic-resistant bacteria. Weight restrictions (typically 250-500 pounds) exist for volunteer safety during body placement and recovery.
Logistical requirements include having a certified death certificate, arranging transportation to the facility, and now getting a postmortem negative COVID-19 test. Most facilities only accept donations from specific regions due to transportation logistics and legal jurisdictions.
The donation process treats families with utmost respect and compassion. As researchers emphasize, donors are contributing to science in a meaningful way—helping solve crimes and identify unknown remains for other families.
Are there body farms outside the United States?
While the United States leads in body farm research with eight facilities, the concept is slowly spreading internationally. Currently, ten body farms operate worldwide.
Australia opened the Australian Facility for Taphonomic Experimental Research (AFTER) in 2016 at the University of Technology Sydney. This facility focuses on a uniquely Australian forensic challenge—identifying bushfire victims. Given Australia's frequent wildfire disasters, this research fills a critical need for local investigators.
Canada operates the Recherche en Sciences Thanatologiques Expérimentales et Sociales (REST[ES]) facility in Quebec. This site provides crucial data on decomposition in cold-weather conditions, filling a significant gap in northern climate research that U.S. facilities couldn't address.
Planned facilities face various challenges internationally. Proposals exist for body farms in the United Kingdom, Netherlands, and India, but these encounter regulatory, cultural, or funding obstacles. The UK has focused on using pig carcasses rather than human remains for decomposition research.
Cultural and legal barriers explain why what is a body farm looks different internationally. Many countries face cultural or religious objections to outdoor human decomposition research. Legal frameworks for body donation and research vary significantly between countries, creating regulatory challenges.
This international expansion matters because decomposition rates vary dramatically with climate, soil conditions, and local fauna. Data from temperate U.S. sites might not apply to tropical, arctic, or desert environments.
Conclusion
Understanding what is a body farm reveals one of the most fascinating intersections of science and death investigation. These outdoor laboratories have transformed from Dr. William Bass's humble 1972 experiment into a sophisticated global network that directly saves lives and solves crimes.
The journey from that first donated body in Tennessee to today's ten facilities worldwide shows how scientific curiosity can create profound social impact. Whether it's the microbial clock research that can pinpoint time of death within days, or the vulture studies that help investigators understand scattered remains, body farms provide answers that matter deeply to grieving families and criminal investigators.
Each facility contributes unique insights based on its environment. The subtropical Florida conditions create different decomposition patterns than Colorado's high-altitude desert, while Canada's cold-weather research fills critical gaps for northern investigations. This geographic diversity makes the difference between solving a case and leaving families without answers.
At American Mortuary Coolers, we see how what is a body farm research complements our work in mortuary refrigeration. While body farms study natural decomposition to determine when death occurred, our custom cooling systems preserve remains so investigators have time to make identifications and families can say goodbye with dignity. Both serve justice—one through understanding decay, the other through preventing it.
The future looks incredibly promising. Researchers are developing artificial intelligence models that can predict decomposition rates based on environmental conditions, while 3D imaging technology creates detailed records of skeletal remains. The necrobiome research may soon provide time-since-death estimates accurate to within hours rather than days.
What makes this work possible isn't just scientific innovation—it's human generosity. The 1,300 pre-registered donors at Tennessee alone represent people who chose to serve science even after death. Their families often find comfort knowing their loved ones continue helping solve crimes and identify unknown victims.
The impact extends far beyond individual cases. FBI agents trained at body farms carry their knowledge to investigations nationwide. Cadaver dogs learn to detect remains that might otherwise never be found. Forensic software developed from body farm data helps identify victims from mass disasters and old cold cases.
As one researcher beautifully put it, "Each donor is of tremendous scientific value and we are grateful to our donors and their families." This gratitude reflects the profound human element behind the science—what is a body farm ultimately about helping the living find truth and closure.
For those working in mortuary services or forensic investigation, understanding both decomposition science and preservation technology provides valuable perspective on death investigation. Our guide on Cold Case Explained: Understanding Morgue Refrigeration explores how controlled temperature environments support the investigative process.
Body farms remind us that even in death, we can serve life. Through careful science, respectful research, and generous donation, these facilities continue advancing justice and bringing peace to families who need answers most.
