Yes, because the dates of death are different on the obituaries. However, if one was alive when they got to her, seems she died on scene because late that afternoon a reporter stated both bodies were still there.
If it's true that the girls died on different days and this isn't just a mistake in the obituaries, then I think it is pretty significant. First off, I would be surprised that LE would let that out there, but perhaps once the cat was out of the bag so to speak there wasn't much that could be done to walk it back without drawing further attention to it. If true, then it was obviously something a family member inadvertently let out. The implications are pretty terrible to contemplate. I have felt all along the the killer quickly moved the girls to a secluded spot so he could have more time with them, and it is likely that they were alive well into the night. Also, forensically it is not easy to pinpoint time of death that precisely so the question would become how did they know that one girl died on the other side of midnight? Did one of the girls take pictures of the scene that the killer is unaware of? Terrifying and sickening to contemplate, the stuff of horror movies. God Bless these poor girls and their families.
