There are commercial properties on the road Linda lives on. Some are building supply companies, manufacturing companies. Were any of those companies open on Sunday, maybe not to the public, but to ship orders or receive materials? Is it possible a trucker(s) from out of the area picked up or dropped off a cargo sometime Sunday? Could a predator trucker have come across Linda?
Sadly sex predators could be anyone.. from those who live there to a complete stranger who saw Linda vulnerable, and alone. It doesn't even have to be trucker.
Predators are opportunist unless they specifcally target, and stalk them before the kidnapping.
They may have either already kidnapped, and sexually assaulted victims before even other cities or states, and if they haven't they have long fantasized exactly what they will do when they kidnap their first victim. They are even known to carry a rape kit, and even a kill kit in their vehicle at all times.
For all we know they may be from Lancaster or another area close by, and was in this area at the time for whatever reason, and then quickly returned once the abduction, rape, murder, and discarding the victim's body were over with.
That's one of the most terrifying things that has to be considered about any sex predator. They are anywhere, and everywhere, and come from all walks of life.
It literally could be anyone, and location still unknown.
It could be someone from there who is hiding in plain sight. Someone everyone would least likely suspect.
If the suspect is ever found it may become known they have a history of sexually assaulting their own family members, who have been too fearful or ashamed to tell anyone.
It isn't that uncommon for rapists to escalate to the violent crimes of kidnapping, and murder. Raping victims no longer satisfies their twisted evil deviancy. This is true with pedophiles as well as rapists who targets male or female victims.
However for now I think the kidnapper of Linda is probably still close by. He may even be very interested in her case or even partakes in searches himself.
He still very well may be a stranger predator that Linda only facially recognized in passing. If so, he would know LE wouldn't find any kind of familiar link between him, and Linda.
He may have even targeted her because he knew she was a victim not linked to him or his own family, and friends.
I just pray Linda is found, and the suspect is too. The longer it goes on more, and more vital evidence is being lost.
My heart breaks for her family.
