The gory tableau at the Mullins' family home in Mustang includes a man who appears to have been run over by a truck and another whose head has been squashed under a garage door - complete with fake blood splatter.
The scene has drawn gawkers and some concern. At least one woman called 911 to report the crushed head; emergency personnel responded and discovered the dummy.
Thirty-two-year-old Jennifer Mullins says she was inspired by the social media website Pinterest.
She says Halloween has always been a favorite holiday for her family and that they knew the display would raise eyebrows - but perhaps not that it would win them quite so much attention.
