Why blow up [SPOILERS] house?
I just put the tag in there in case anyone hasn't seen it.
The villains take such care to make Amanda's death look like an overdose, an accident. Yet when they kill Dixie to keep her from talking to the cops, they blow up her house? Why not just kidnap her and make it look like she left town, which would be believable? Bury her out in the desert somewhere. Instead they nuke the house and the cops find the device. Even if they didn't know it was a Special Forces doodad, they would have known it was murder, and reopened Amanda's case.
