Emily Craig, the only full-time state forensic anthropologist in the country, is retiring Nov. 30.
She said her 2005 total knee replacement limits her ability to get into rougher terrain.
Craig's work has long been recognized nationally. As a student, she helped to determine that Branch Davidians leader David Koresh had died of a self-inflicted gunshot wound to the head.
Later, she found evidence in Oklahoma City that helped convict bomber Timothy McVeigh.
Called to assist after the terror attacks of Sept. 11, 2001, she worked for weeks in New York, sifting through the ruins of the World Trade Center for body parts.
Some of the work she is proudest of, she said, is teaching Kentucky's coroners how to conduct death investigations. She is expected to continue consulting after some time off.
