" Insufficient evidence ".
A strange reason to let someone free considering the seriousness of the crime ?
I could understand if the police said they have let him go because of mistaken identity.
So if they are not sure he was involved or not and let him go, I would fully expect this guy to have full surveillance on him 24/7 and if he is involved he could lead them to who maybe also involved. That's the only reason why they would release him other than he is completely innocent I would imagine his DNA is not at the scene though.
