Church Street pick-up.....
The Eddy County Sheriff's Department has always known more than they have been willing to say. After this long, that info about a Church Street pick-up or abduction should have been part of the public record with witness statements to back it up, and you, SS1950, weren't allowed to have it.
In the mean time, they've lost evidence, and it's hard to say whether they've messed up this investigation with their own ineptitude or whether there's been a cover up as you've suspected all along. The truth needs to come out, and I don't think you're going to get it out of them at this late date either. So it's time to go the route we talked about, get the answers, and bring this farce to a halt.
If this Church Street pick up or abduction site has anything to do with someone or several in Eddy Co. Sheriff's office still trying to lay blame on McGrew, then I think for sure this is a cover up because I don't believe for one second that man could come to your house over and over, been so comfortable around your grieving family, and have committed this crime. From what you've said about McGrew, just the opposite was true, that he was a caring man, concerned with bringing justice to bear on the person or persons who committed this crime, and was shot for his efforts.
They are going to find themselves in a heap of trouble if no autopsy was done on McGrew, and in trying to explain how evidence has been lost in this case, and they will have to explain it! There is no excuse for losing evidence. So maybe they will turn that place upside down and find the things they've lost.
Skip the letters to the senators, and go to the one person we talked about who can do something. There is no time to spare. You will need to name the names of the investigators who tried to reopen this case in 1973?, and whose efforts were dismissed. Those are old men now, and what they might remember is of utmost importance here.
Legacy can probably provide you with reasonably current addresses and phone numbers for them if they are still living. She has an Ancestry account, and I know she can access more current information through it if given a general idea as to their whereabouts.
Didn't I read in one of the newspaper articles on Deputy McGrew's death that he had been advised by his doctor to see a specialist in El Paso? That could mean that he had some type of serious illness, and in 1961 if you were diagnosed with something like cancer it wasn't anywhere near as curable as it is today. Unfortunately, people looked at it as being a long slow death sentence and if they didn't have adequate coverage it could cost them every cent their family might have.
Also, another thing that I have learned is that New Mexico is one of the very few states in which polygraph results are admissable in a court of law under certain circumstances. This is something that WDB might have been aware of because of his prior problems with LE and the reason that LE could never catch up with him to take the test.
I think one of the big problems with the loss of evidence is that in the beginning the New Mexico State Police colected part of evidence and the Eddy County Sheriff's Department colected part of it. The reason I say that is because Estrada stated in his report that he visited with someone with the New Mexico State Police at a get together and got some of the evidence. I would have thought that one agency would have been responsible for the custodianship of the evidence, but I guess in this instance not.
