Texas Is Home to the World’s Largest Body Farm

Tucked away on 26 acres in San Marcos sits an outdoor human decomposition research facility, funded by Texas State University. The site allows researchers to study how the body breaks down in different environments, offering critical insight into what happens to human remains over time.

The Freeman Ranch is part of Texas State University’s Forensic Anthropology Research Facility(FARF). The “body farm” at Freeman Ranch has human remains spread across acres of land.

The remains are left to the natural elements outside in order to observe their stages of decomposition.  Students, researchers, and even law enforcement agencies use this unique research facility to better understand how to accurately assess time since death based on body decomposition.

Photos and videos shared online offer a glimpse into how research is conducted at the ranch. One of the most important aspects of the work is creating realistic scenarios that mirror what investigators might encounter in real-life cases.

Some bodies are placed inside large wire cages to protect them from certain elements or scavengers while still allowing researchers to observe natural decomposition. Others are left fully exposed to the environment to replicate real-world conditions, including natural wildlife activity, such as vultures feeding, which can significantly affect how remains decompose.

Once the bodies are fully decayed, the bones are collected and permanently stored in the Texas State Donated Skeletal Collection, where they can continue to be analyzed in future research.

Since FARF opened in 2008, about 650 donated individuals have been part of research on the ranch. Bodies are donated either by family members or by individuals themselves, who can pre-register to have their bodies used for research after their death. Currently, about 1,000 pre-registered donors have signed up.
