Betty Pat Gatliff was born on 31 August 1930 in El Reno, Oklahoma, USA. She is known for Quincy M.E. (1976) and BattleField Detectives (2003). She died on 5 January 2020 in Oklahoma City, Oklahoma, USA.
She worked with Clyde Snow, a forensic anthropologist and colleague at the Federal Aviation Administration's office in Oklahoma City. They developed what is known as the Gatliff/Snow American tissue depth method, in which several short stubs of soft plastic are glued directly to the skull, at different heights according to the average depth of tissue at various points. The stubs act as guides, as clay is spread from one marker to the next.
