Well, yeah, it does seem so, and this sort of points to her alone as well: ( I had actually thought a huge blaze had been set to the house)
“City fire Inspector Damon Robbins said a match flame ignited vapors from a pool of gasoline on the woman’s floor, but the flash fire did not continue to burn and caused no noticeable damage to the house.”
Every one of these “attacks” I’ve read about, as far back as I remember, they’ve been staged by the supposed victim. I think matt Shepard may be the only one that wasn’t the victim faking it all.
