Who Shot Jim Longworth?

The bigger mystery than who shot Jim at the end of Series 3 of The Glades is why did A&E pull Series 4?

So there we are seeing Jim writhing on the floor while his bride, Callie, is waiting for him at the altar (so to speak).


So who do you think shot him?

I think either Callie's ex-husband or his brother (who, when he was shot, expected Callie - a nurse - to treat him and not report it to the police).

Any other ideas?

(I understand that both Matt Passmore and Kiele Sanchez (who played Jim and Callie) are now working on other TV programmes.)
