I am wondering if this was a hit and run case. The elderly gentleman who discovered JR's car said at 1:10 into the video,
"she was in the wrong lane to go to Cambridge." So this is where the information came from that her vehicle was facing the wrong way HTH. He also said he saw no one in the front seat (through tinted windows) but suggests perhaps they were on the floor of the car. Perhaps JR wasn't wearing her seat belt and was thrown inside the car upon impact...if that was the case? The fact that no safety warning/threat to the public has been put out, almost makes me believe this is an isolated incident and it's just a matter of time before they solve it.
If JR's vehicle was hit, LE could be waiting for test results (paint or pieces of the other vehicle) to come back with the type of vehicle that hit her car? It's amazing what information they can get from paint. If it was a hit and run, maybe once testing is done from evidence, LE might release more details asking for the public's assistance in helping to solve this case. They may ask the public if they know anyone who owns a certain make and model of vehicle, to contact LE if they had notice any damage or that person's vehicle out of commission for a while. They may also contact body shops asking if a certain make and model of vehicle has been in to have body work done since this case.
Regardless, I hope her case get solved and there is justice for Jessica and her loved ones. All MOO.
