Texas Chainsaw 3D
Before Heather's heritage was revealed, he was very warm and friendly to her and showed genuine concern. She even admits, she found him nice.

While at the station, Heather learns of what the townspeople and his father did to her family and flees. He soon catches her, and ties her up at the long-abandoned Sawyer slaughterhouse to lure Leatherface. He then leaves the slaughterhouse before Leatherface arrives and doesn't witness his father's death. Most likely, like Heather's adopted parents, she had Leatherface exact her revenge on him or he was apprehended by Sheriff Hooper for helping with his father's vigilantism. Though his final fate is left to guess at best.
