I've been thinking about this case and trying to figure out what the motive was? We know the wife of the victim has been accused by the suspect's wife of having an affair with the suspect. But, LE hasn't yet arrested the victim's wife, so could it be possible the suspect did this without the victim's wife's knowledge? What type of a scenario would it be? Why?
The suspect had been married for over twenty years, with three children, a decent job and appeared to have a good life. But within two weeks after returning from a business trip that included the suspect and the victim's wife, the suspect's whole life was turned upside down!
I've known married couples where one cheated and completely blind-sided the other spouse. I mean, their marriage appeared to be long-term and very loving. There was no 'reason' for the offending spouse to stray. (To this day, they don't even know why they did it.)
But if the suspect and victim's wife had a tryst while on that business trip, which wasn't planned (the affair), but like they say, just happened, ...............it's possible that one of the innocent spouses could detect a change in their partner and figure out what had happened. They could have confronted their spouse and after much contention, gotten them to admit the brief affair.
Now, this couple that I knew, the innocent spouse had done some reading of what to do when you find out about and confronted your spouse about their indiscretion. One thing was to contact the spouse of the other party, and tell them what happened.
What if Rusty found out about the brief affair and was determined to try to make their marriage work. But one of the things he did, was to contact the now suspect's wife? That COULD account for them separating right after returning from the over-seas trip. The suspect's wife wasn't so understanding. You never know what you'd do in such a situation. Perhaps the suspect's wife, unlike the victim and his wife, threw him out of the house?
That could really allegedly enrage the suspect. The victim tells his wife and he looses his family!
They said this crime was up close and personal. Almost like a hit, but there was sign of rage as well. Very methodical, planned, no emotion showed by the perp to anyone that witnessed the crime. (he MAY have looked on this just as another PROJECT, he is an engineer).
IF there was anything within the digital communications between the suspect and the victim's wife, LE would have already arrested her, IMHO. Or, perhaps they're HOPING there will be some connection at the time of the suspect's trial. Like others have said, time is on LE side.
It'll be interesting to see what was in the electronic communication. AS may have been completely blind-sided by this heinous act! But her alleged indiscretion MAY have been known only to she and her husband and the suspect and his wife. When Rusty was gunned down she may have not even connected the two and she certainly wouldn't want the info of her cheating to come out. As a matter of fact, she MAY be horrified that it is her former boss and alleged parmour.
Just some thoughts,
