Another thing. Ross overhears Lawrence say, on Thursday 24th when Lawrence returns to the pub in Emmerdale from holiday with Bernice, that he has the gun Lachlan found in the village in his Home Farm safe.

Maybe Lawrence later does a deal with Ross, so that Ross is the hired hitman who shoots Robert on Friday Sept 25th in return for Ross to have his gun back from Lawrence and to have Chrissie's bracelet as reward. (Aaron still has a gun to dispose of though, so where does this come from and why is it so sensitive that Aaron is so upset about it?)

Ross tells Debbie that he is leaving Emmerdale on Friday 25th, after Robert gets shot. Just what else would a hired hitman do after a job but leave town? Is this coincidence or what?
