Well, believe me, my "dad" would have been the drunker of the two drunks having a conversation. Our thinking is that he gave out too much information - where she lived, that she was alone, that she "took everything he had", she's a rotten ***** and he'd like to see her dead, etc. I don't THINK "dad" thought someone would take that information and actually act on it, if that is what happened, I don't believe they did it on his behalf, BUT I am not ruling anything out or letting anyone off the hook yet.
As far as Taylor, the way "dad" and his friends behaved at the time of her death was more of a pity party for him. One of them said some pretty pointless things to one of my brothers when we were all together that next night and it was just about more than I could take. No, they did not have any clue the loss, complete devastation, that we all felt, most especially my brother and sister-in-law. That was in the middle of the divorce and that was "dad's" focus.
My "dad" has done such rotten things to my brothers as retaliation for all of us standing by our Mom in the divorce...I won't even go into all that. But I will never cut him any slack for his behavior. He brought it all about himself. Every. single. thing.
I agree that nothing should be ruled out. If your father was drunkenly talking to someone in bar, or elsewhere, i would think that if the person he was telling this to is the perp, there would have to be something that motivated him to kidnap and lord knows what and where take your mother.
To do harm to another is such a horrible thing, even if your dad told them drunken stories about your mom, most people wouldn't harm another or risk being arrested doing something.
There would have to be another factor involved, that the perp would have to be getting something out of this. It may not be something material, like money, it could be something else, like approval from your father.(approval being either real or if the perp is delusional, they may think your father would approve, when in reality he may not).
Do you know if your father or his new wife/girlfriend have any friends that may seem a bit "off" or mentally imbalanced?
The only other way i could see someone kidnapping, harming another human is if they were getting some type of personal gain, maybe promises of money, etc, if they were "hired" or paid to do it.
At the time when Taylor passed, the pity party behavior by and for your father is very pathetic in a sad way. I have seen others behave as such before. (My father in law was dying of cancer and his brother was over complaining about all his own health problems diabetes, etc, nevermind my FIL was literally dying of cancer. That type of "pity party" is very sad, as it seems the ones wanting pity are looking for attention from other family and friends yet the timing of wanting pity is horrible.
So i've never quite understood why people do that, however i am sure that depression is the basis of that as well as alcoholism. I can guess that maybe they don't know how to make proper conversation if they are "black sheeps" of a family, maybe they use the oppurtunity of the family gathering for a death to try and get sympathy from family who wouldn't otherwise seem them and show it? It's anyone guess, it's hard to understand the behavior and it may vary depending on the individual. The common ground seems to be that the individuals are depressed.
Depression is the basis of anger, hurt, sometimes people's emotions don't always come out in the exact emotion they are feeling.
Your father's friends seem to be pretty loyal to him..
Do you know if his new wife/girlfriend has any children? If so, are they around your father and friendly with him?
If you don't mind be asking what times of things has he done to your brothers out of retaliation?
