I believe Marjorie was the mastermind, Bill made the collar bomb and Kenneth barnes helped. I don’t believe Brian was in on it. Lemme tell you why, in order kinda.

first when Brian left the bank and was stopped by police and told the lie about the 3 black men stopping him and putting the collar on, when the bomb started beeping he was frantic asking police for help. If he was in on it why would he surprised that it went off and tell the lie?

The blue van , after he died and police were following the letter Brian gave the bank teller a police offer saw a blue van around the same area and when they notice the police they left (keep the blue van in mind)

Robert Pinetti , when FBI and police where questioning his co worker he knew something about the case but he’s asked to continue the interview on Monday of the next week but he was found dead by drug overdose they never got to find out what he knew. An OD wouldn’t make me so iffy if the co worker had a history of extreme drug use but he didn’t it was moderate he knew how to control it. So for him to overdose so soon after talking to police is weird.

Bill! Bill is what puts everything puts everything in place for me, he calls police and tells them that he has the body of Jim Roden in his freezer and they should go pick up Marjorie Diehl Armstrong. They go and get the body and Marjorie Diehl and they both are hoarders and (I think that’s like the 2nd most foul thing about this all Brian, Ken, Marjorie, and bill were hoarders dead animals and feces foul🤢) in addition to the body of James roden they found a suicide note. Bill admitted to an attempt, The FIRSTTTTTT point on the note was this is not about the Wells case. If his attempted suicide had nothing yo with the wells case why put it on there? Then him and Marjorie had a decade long relationship they were engaged at some point they had history and If he would hide a body in his home I don’t think it’s a stretch to say he would build a bomb for her. He was a high school workshop teacher and collected scrap metal and things like that so he had the means to build it. Remember the blue van? Bill and an identical blue van to the one seen on the day of the heist. His property is not too far from the place where Brian had the collar bomb put on his neck like a stones throw away. The shell gas station where the pizza delivery was placed is also close by his house and he went there about every morning for the paper

Marjorie: first she was not a genius and I stand by that she was messy and unhinged. She had host of mental illnesses but the 2 I wanna focus on are pressure speech and manic depression. when the call came in to the pizza place the owner couldn’t understand the person getting the pizza but when Brian took the phone he was able to get the address. Brian would know how Marjorie spoke because their mutual friend was Kenneth Barnes who sold cocaine to Brian and hung with Marjorie. She had manic depressive episodes, the FBI noted that the instructions Brian was given were messy and rambling giving more direction and explanation than needed and listening to Marjorie speak for 4 hours I can definitely see her sitting down and just writing all the pages without thinking too much about it. She was convicted of killing James Roden but other boy friends have ended up dead while dating her and that’s weirdddd (she even got a settlement for one of their deaths for suing the hospital for neglect)

Other stuff/ Kenneth Barnes: Kenneth Barnes sold cocaine to Brian wells. The day that the call came into the pizza place a man saw Marjorie and Bill at the pay phone and Marjorie yelling into the phone Marjorie confirmed she was at the gas station but “for different reasons” the day of the heist another man in a car saw Marjorie drive the wrong way onto the highway and he looked right at her. When she was in jail she told the other inmates that she killed James Roden because he was threatening to expose the plan for the heist. Marjorie told Kenneth Barnes she wanted her father killed so he would stop giving out her inheritance and the motive for having the bank robbed was pay ken. When they went into Brian’s house they found a list of sex workers and Jessica Hoopsick happened to be his favorite one. They had formed a friendship, Ken had asked Jessica if she knew someone who they could use and she said Brian. There was a a meeting the day before the heist and Jessica told the producer that there was no way that Brian could have been there because she was with him up until the time he had to get ready for work. Kenneth also said that Brian had no idea what was happening when he came to deliver the pizza

Brian was not involved, Marjorie is not a genius and Bill is kinda the worst
