@8:31 His admission of guilt was a strategic move (to get out) or a statement of truth, or both. These two possibilities are not mutually exclusive. @10:23 "The number of matching fibers was only 7." If he wasn't there, the number should be "ZERO".
@leep6889 It is possible that the two are classmates of each other, but not of the victim. Somehow, the press was misled by the defense attorney to think differently.
he needed to admit he did that to get out of prison. the legal procedure is like you need to admit crime or else you still no regret then cant let u out of the prison
