No.Who says it's going to be a next trial? Their two biggest witnesses Jen and Jay can't be put back on the stand again, which would make it difficult to convict him again especially considering that those same prosecutors that helped convict Adnan helped Jay out years later after he got into other trouble.
Two big witnesses changed their mind after the years went by and I do not believe the DNA will prove anything.
I already suspect something would be in the car, he was her boyfriend for a grip.
But, Jay's story will not hold up and he's the main one saying he saw the body.
Plus, the suspect who had a relative live next to where the car was found seems like the one.
