Little Boy Blue - Season 1 Episode 3 -

Dave believes he has a lead when Kevin Moody, encouraged by his sister Sandra, admits to the police that Mercer gave him the gun but the crown prosecutor still feels there is insufficient evidence to proceed. Dave hopes this will make the culprits more confident about getting away with it and steps up his pursuit. There is a set-back when Claire Olssen is bullied by the killer's family and gang into giving a false alibi so that Dave is relieved when Kevin finally agrees to enter witness protection and names Mercer and his associates, thus making arrests possible.
