Sergeant Pat Mallory:  Patrol responded to a 911 call . Victim is male , white .
Kevin Bernard: Oh . Kid is _ sixteen _ ; seventeen , tops . Looks like a single stab wound to the chest .
Sergeant Pat Mallory: My guys are looking for a weapon .
Cyrus Lupo: Five dollar bill and some change . No wallet , no ID .
Sergeant Pat Mallory: Could be a rich kid from the neighborhood with that preppy outfit .
Cyrus Lupo: Preppy , maybe . Rich ? No . Look at his cuffs . They 're all frayed and his pants are too short . Hand me downs . He shops right out the bin at Goodwill .
Kevin Bernard: Fresh haircut , nails are clean . He 's too well groomed to be living on the street . He even tucked his shirt in .
Cyrus Lupo: And he buttoned his top button .
Kevin Bernard: Did you ever walk around like that when you were his age ?
Cyrus Lupo: Not unless my mother made me .
