From your link and bolded by me:
Is this new information? I read back on the thread and also through some old msm articles and couldn't find anything about Egypt being bound. So if that's accurate then according to LE they believe her murder wasn't random, it was someone she knew, there was no evidence of forced entry and now we learn she was bound.
Lt. Bazzy said they're still waiting on lab results (maybe that includes DNA) and hopefully when all the forensics are in they'll have enough for probable cause. IMO they've had someone in their crosshairs for a while and will move to arrest soon.
