What is Guts Man?

The anatomical model of a human body found in the conference room of the OCME. Its plastic organs and body parts are removable and its intended use is as a visual aid for explaining to family members how a crime victim was killed. Scarpetta spent a great deal of time consulting with bereaved family members when she was the Chief Medical Examiner. She is chagrined to see that Guts Man has become dusty from lack of use under Dr. Marcus' tenure and assumes this means Marcus doesn't bother to spend much time with the victims' families.
