I respectfully disagree with your theory of TT being a triple murderer. You are giving him way too much credit. For him to interact with the police within hours of committing a triple murder, disposing of bodies and remaining completely calm is pure fantasy. Competent or not if FWPD really thought he was the actual killer they would have found a way to burn him one way or another. We can walk through this scenario in another thread if you like.
What I am absolutely convinced of is TT and Debra share a "secret" that would have broken this case wide open had they cooperated with FWPD early on. I don't believe either of them actively participated in the disappearance of the girls. This "secret" is not about them having relations either.
This "secret" has caused Debra angst her entire life.
All of the families know deep down she has never told the truth the whole truth and nothing but the truth.
As far as FWPD being incompetent, that is debatable. What I do know is in 1974 FWPD was ruthless and vindictive if they felt they were being played. There is a clear reason FWPD would want this case to go away, but I'm not going to post it here. It is a purely speculative and dangerous scenario.
I completely dismiss the theories that the girls were the victims of an interaction with a stranger(s) who kidnapped them using a weapon or a "strong arm" technique.
These girls were lambs that walked right into a trap.
Let's look at a PURELY SPECULATIVE scenario of what realistically could have happened the day they disappeared.
First they go to Army -Navy and Renee picks up her layaway. Julie stays in the car as best we know. Maybe they make it to Seminary South maybe the don't.
The girls make another stop. This is where the girls meet their end. This is the "secret" that TT and Debra know. TT and Debra know enough about this stop to be absolutely
terrified when the girls come up missing.
Keep in mind we're talking about juveniles.
Not only do TT and Debra have legal exposure if they tell the truth about the reason for the stop, they would have to explain how they know about this stop to all of the families and what the ugly truth is.
On top of this they have to worry about their own safety. They don't fully cooperate with law enforcement for these reasons.
This is the worst possible position for them to be in.
The letter isn't an attempt to buy time or divert FWPD. It is a message to the people at the stop that we're not going to finger you.
Plant this in your brain box garden and sprinkle a little water on it:
Decent people put themselves in situations with others they would NEVER interact with normally when they go to cop.
People get robbed and/or murdered every day when they go to cop. The deal can go bad at the drop of a hat. It is an indisputable fact.
One thing that will get you killed in this world regardless of your sex or age is if someone thinks you might inform on them and send them to prison.
Who got booted from their apartment for non payment of rent and yet had a job. How do you explain this?
Who worked in bars? Best connects ever are people who work in bars.
The main reason Renee wanted to be home by 4 was so she could go to a party.
Absolutely no disrespect to the girls. They are as innocent as a driven snow.
Drugs, deceit, theft and violence fit like hand in glove.
FYI, some background info on me.
I graduated from Southwest in 78. I had just turned 14 when the girls disappeared. Renee would have been in my graduating class.
I lived on Lawndale, two streets over from Minot. To say this case hits close to home is an understatement.
