Keep coming back to the thing that a friend of the girls said. That she looked so much like libby that her Grandparents could not tell them apart. This girl was friends with both Abby and libby. Mistaken identity by the killer?
Just remembered TB. All his victims look more or less similar. Especially in the beginning, when he was probably “taking revenge” on his first girlfriend. (Interesting that he spared her, but it is explainable: they were connected in history by having a long, passionate, affair. The police would have found him if the one who broke his heart were killed.)
So Bundy “vindicated” other women, who resembled her, in looks and even career (high college students). Maybe clothes they favored, maybe the way they smelled.
This being said, there were other women around him, whom he never touched. Liz K., and then, the future mother of his child. And probably, many others who were attractive enough for sex, but not resembling his first love enough to be killed.
(At the end, he got off the rails and off the stereotype, but if you pull out photos of his early victims, they looked almost like clones).
So, maybe LG was a mistaken identity, or maybe, he is attracted to such women as victims. Maybe one of them made him too angry once?
Could be LG or her sister Kelsi, or that girl who looked so much like Libby, or some of their female relatives.
What makes it easier, seems that among ethnic types in that area, there were many looking like Libby.
