I sure would love to know what LE have uncovered about this case that they are not sharing. At this point I really can't believe that they have not been able to identify the owner of that dark truck, even if not, the driver. I would almost bet money that they have retrieved a lot of video from the Sherwin Williams plant, Lowes next door, and probably some of the other buildings in that industrial area near where Naomi's car was found. Surely they have seen the license plate, unless there was none on it. And I would think running DMV records for Nevada, and even neighboring states should be able to yield owners of vehicles that match the truck. Then it is just a matter of whittling them down until you get your owner. They have probably been able to pin down the time her car was left where it was found. Also, her car has almost certainly been processed fully by now, so hopefully that revealed some clues to the identity of her attacker. They also probably have seen better video of the perp at Walmart, as the store has many cameras, covering all of the property.
I am not sure how much major crime Lyon County has had to investigate, so do not know how well-qualified they are to handle this, but the FBI is involved, with all of their expertise and resources. Hopefully, this case is progressing and Naomi will soon be located, hopefully alive and well, and whoever took her will be held fully accountable for this despicable crime. JMO
Police always operate with the assumption that the victim is alive. No bones means possibly alive. If police had identified the driver of the truck, that person would be brought in for questioning. It would be a person of interest, not a suspect. The assumption that the victim is alive means moving fast - not sitting back waiting for the person of interest to make the next move.
In my opinion, investigators have not identified the owner of the truck, or the truck is stolen and they don't know who stole the truck.
I agree that it's a process of elimination reviewing all sales of that make/model/colour truck with that detailing in NV and surrounding States. It's less than 3 years old, so the owner registered it for warranty purposes. I wonder how long it will take to narrow down the list.
