I don't believe it was just a triggering event, whatever happened was premeditated... Due to the fact he called, or someone else, at least a couple days in advanced to "see" the house. Premeditation like THIS usually has a motive other than to kill just to kill. Imo
Oh I definitely agree with you on the totally premeditated part. I don't have one doubt in the world that he premeditated all of his acts. He took time to select his target. Look at how the A-train planned to kidnap and murder Holly Bobo and none of them had ever even associated with her. Premeditated kidnapping and murders of defenseless females have happened many times by those the victims really never even knew.
Just because he premeditated his crime doesn't mean there is some hidden motive for doing so, imo.
But that still doesn't mean there wasn't a triggering event around the time this all happened. Even SKs who kill for no other reason than they like to kill .....do have trigger points and events in their lives that makes them act out when they do. And all of their crimes are certainly premeditated and calculating before they strike.
He seems to be
'a whiney blamer' so instead of making his own life better and more secure he takes out his rage and hatred against someone that, according to him, seems to have everything and someone he knew would be terribly missed. He didn't want to kill a no body for he wouldn't have gotten much attention that way. He wanted to make a big statement by who he selected as his target.
I don't think he is one that kills because they can but he sure is an attention seeking killer. IMO.
He wanted to murder someone that he perceived as 'rich' and he picked Beverly because he knew she showed houses alone.
And female real estate agents have been targets of kidnapping, rape, and murder going back years. Unfortunately several have lost their lives by showing someone a house while alone. Even two young women in Georgia were raped/murdered inside an open house they were showing. He had premeditated it all and pretended to be a home buyer. He had been sizing them up before he came in with every intention of raping and murdering them.
And Sara Walker out of Texas was also a real estate agent and was brutally beaten to death by a man she didn't know. A man who turned out to be a ex-felon.
I have kept up with these cases since I owned my own real estate company for 16 years.
One of our daughters who lives is Charleston is also a real estate agent and I immediately sent her a link to this story.
