@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".
I think he did it due to the environment and prove. i feel very sorry for the girl as so young and have bright future. I think Mr. Au Yeung don't regret up to his death as not say the truth
