He is not "factually guilty". The cell tower ping evidence was basically all the "science" the state had against him, and it was the foundation for the constantly evolving and self-contradictory claims of the state's key witness, Jay Wilds.
I don't know what Jay's deal is (seems very implausible that he was the murderer), but with the cell tower pings being all but useless for tracking location, then Jay's stories are just circumstantial claims.
(again, it can't be emphasized enough how nonsensical and mutually contradictyory all of Jay's stories were over the years)
I gotta do my due diligence and source this but I think there was a podcast called the "truth and justice podcast" that found a interview with the head of police before Jays testimony that said the police had located the vehicle and were withholding the location from the public at the time.
This means the police already knew about the whereabouts of Hae's car before Jay. This part gets slightly more conspiratorial but the police could have lead Jay to the car instead of the opposite.
Agreed, it's possible. Though we'd also need to explain why Jay is still sticking to a made-up "I buried a murdered woman" story decades later. And find the "real killer" who happened to murder Hae the same day Adnan loaned Jay his car and phone...

How Jay came to know where the car was parked is indeed confusing -- because it's hard to believe how the cops could know about it before him, which would presumably be a prerequisite for the cops conspiring with Jay to frame Adnan.
But according to the state's motion to vacate[0], the car was parked near the home of one of the current alternate suspects, i.e. one of the suspects whose existence the cops and district attorney for unknown reasons, illegally withheld from the defense. So I can't explain why Jay would know where Hae's car was parked, but that mystery is ultimately superseded by the mystery of the police's handling of the alternate suspects.
I have changed my comment to add 'I believe'. But I do think that if you simply look at the basic evidence you can only logically conclude that he is guilty. Certainly Jay has tried to paint himself in the best light possible, but he admitted to helping Adnan and took the cops to the car. Adnan admits to being with Jay on the day of the murder. This alone means that if either Jay or Adnan are telling any form of truth, then he is guilty. While obviously not evidence enough for conviction, the fact alone that Adnan never tried to call or page Hae after the day of the murder, even though he had continued to reach out continuously prior, has no other explanation in my view.
