From Texas Public Radio:
In a murder investigation, establishing a time of death can help lead to arresting and convicting the perpetrator — or exonerating someone wrongfully accused. That’s why getting it right can mean life or death for someone like Texas death row inmate Larry Swearingen. He is facing execution Wednesday for a murder he says he didn’t commit.
The science of “time of death” is something studied every day at the Forensic Anthropology Center in San Marcos, also known as “The Body Ranch.”
