At least, that's what I assume is happening in this still image provided by CBS, in which the boy wonder touches a "corpse." His look of horror is so intense, you'd think his voice just cracked for the first time.

The Daily Mail says the above photo was taken "in a break between filming," which is too bad, because if Justin Bieber's CSI cameo included slapstick comedy, it'd be must-watch. The show's producer said Biebs "did a really good job" in his role as a juvenile delinquent. [Daily Mail]
