Cayce is a suburb of Columbia though, part of Cayce is in Richland County. Columbia is huge and like any big city has crime to match. It's not a stretch to think someone in Cayce could commit a crime and think they could get away with it because of the population density. Especially if 1) they weren't an RSO but knew some lived nearby and 2) didn't expect a police lockdown. I'm so sorry for your loss and your family's loss. However I thank you for this very beneficial insight. For those of you debating DNA, and I can't believe no one has said this yet unless I missed it, with her being asphyxiated she probably fought. There would be his DNA under her nails. That would explain, to me, why at the Friday pc when asked about DNA Antley started to say no but then realized he shouldn't and instead said something about not being able to divulge that at the time. Because they wouldn't have known until the autopsy when the ME who did it scraped her nails.
