1. THE GUILTY REMNANT DID IT!
In the middle of a town hall meeting, Dean suggests that perhaps the G.R. was responsible for Gladys’s death. It seems a little self-serving...until we begin to consider other factors. The opening of the episode shows Gladys sitting in the office of the G.R. Tears are in her eyes. Since we are unsure of the timeline of some events in the episode, this could be a scene that is later referenced – when Gladys found out her son had been killed. However, it’s also possible that Gladys had just been told of her fate by G.R. leadership. Could she have been martyred for their cause?
2. DEAN DID IT!
Could Dean have been intentionally trying to throw the scent off himself with his G.R. finger-pointing? We have already seen that he has no love for the G.R. His aggression against the dogs of the town has made it clear that he’s not afraid of violence and gruesome scenes. We also know that he’s been sent by unseen forces to help the people of the town. Is he capable of killing a person? Could he have been sent to coordinate the elimination of the G.R.?
3. THE GOVERNMENT DID IT!
When Kevin finally gets to speak with the ATFEC agent in D.C., he suggests that there have been orchestrated killings of G.R.-like groups by the government. When we see Gladys meet her fiery fate at the end of the episode, we also see that there are many other bodies in a similar state.
4. THE TOWNSPEOPLE DID IT!
The people of Mapleton have not done much to eliminate themselves as suspects in the murder. They voted against the safety of Chief Garvey’s curfew. Perhaps they know they don’t need to be protected from themselves, if they are responsible. We’ve seen stones used as weapons in Mapleton before. Matt Jamison helped a few members of the G.R.after they were assaulted with stones thrown from a moving car. Matt was himself assaulted in the same manner a few moments later. Max and several other of Mapleton’s youth also seem capable of such heinous acts.
5. REV. MATT JAMISON DID IT!
Could the shepherd be pulling the wool over our eyes? Even Kevin brings Matt in is a suspect. The G.R. did buy his church and paint it white. The two seem to constantly be at odds. Stoning someone to death is certainly a punishment a man of the Bible would be familiar with and might subscribe to. Could Matt’s mini-sermon from The Gospel of Thomas be a red herring to keep Kevin off his trail? He seems like an obvious choice, which in a show so mysterious might quickly eliminate him as a suspect. Or perhaps that’s exactly what he wants us to think.
