'Riverdale': Who Shot Hiram Lodge?

Hermione

Hiram's wife is probably the most prime suspect and not just because it's usually the spouse who did it. Hermione has been increasingly uncomfortable with some of Hiram's actions, largely playing along because she has to. However, after Hiram is show we see her telling FP that it's "time" for something to happen. It's not clear exactly what the something is, but next thing we know, FP is sheriff -- something that absolutely wouldn't have happened on Hiram's watch.

So, while Hermione probably didn't pull the trigger herself, there's good odds that she ordered it.

Archie

Another strong suspect, Archie has a lot of reasons to want Hiram dead and he had the opportunity to take a shot. Archie freaked out during the SAD and left the test, disappearing presumably for several hours that coincide with when Hiram was shot. It's also worth noting that part of what's been freaking Archie out is the hallucination he had in which he killed Hiram. He's definitely worth considering.

Fred

Fred is another character with strong reasons to want Hiram dead. He also threatened to come after Hiram if he touched even a hair on Archie's head earlier in the episode. While Fred isn't necessarily the most likely character to have pulled the trigger, that threat may come back to haunt him.

F.P.

While we have no idea what he's doing with Hermione, F.P. is clearly working with her in some capacity. He also has some serious reasons to want to shoot F.P. given that Hiram has done some pretty awful things to the Serpents and Jughead. It's also not entirely clear where F.P. was when the shooting went down.

Reggie

With Hiram harassing Veronica's business and Reggie having a thing for Veronica as well as being a friend of Archie's, it wouldn't be too far a stretch to see Reggie trying to take Hiram out. He's something of a longshot suspect largely because his feelings for Veronica could also be a reason why he wouldn't take a shot at her father, but this is Riverdale. Anything is possible.

The Evernevers

With The Farm being interested in the same property as Hiram, we wouldn't put it past the creepy cult leaders to try to take Hiram out. After all, it wasn't long after Hiram was shot that the cult announced they had bought the old Sisters of Quiet Mercy property. Seems shady.

Alice

Of course, it's possible that the Evernevers didn't actually pull the trigger. They may have just convinced one of their faithful to do it and Alice is certainly faithful. She's also more than a little morally flexible, as evidenced by the fact that she forged Hal's signature and stole all of Betty's money to give the cult as a down payment on their new headquarters.

Penelope

Hiram promised Penelope a brothel and so far, that hasn't come to fruition. It might just be enough to tip her far enough to try to kill Hiram. She also wasn't particularly thrilled when Hiram attempted to force Claudius into becoming the sheriff. Penelope may not be the most likely or obvious, but she's definitely a possible suspect.

The one thing that is certain, no matter who actually pulled the trigger, Hiram had it coming so it will be interesting to see who really tried to take him down.
