- "Me and your family go way back."
- ― Burt Hartman, to Heather Miller about the Sawyer family
Hartman is one of the first to not be a member of Leatherface's family. When Leatherface was about to be taken in, Hartman took the law into his own hands and led a lynch mob, seemingly killing all the Saywers. He and the rest of the mob where hailed as heroes, and Burt becomes the Mayor. Unknown to him, Leatherface survived and fled to his grandmother's house and the baby, Edith was raised by the Miller family under the name Heather. Decades later Heather inheirits her grandmothers mansion, Leatherface turns up. It isn't long before word gets out that Leatherface is still alive and Heather is a Sawyer, so Hartman takes his vendetta out on her. He has her abducted and taken to a slaughterhouse, where Leatherface eventually turns up. Heather sides with her cousin and Leatherface personally fights Hartman until he forces him into a meat grinder.
