Well, one thing seems pretty certain, and that is what the shooter THOUGHT was going on.
The "professional relationship" may have been completely innocent and just that. Then again, sometimes even the people closest to a wayward spouse (spouses, parents, children, closest friends) are not aware of what's going on, even with affairs that go on for years, so it wouldn't be a stretch that business acquaintences or casual friends also had no idea.
The other certainty here is the husband was a moron. Even if there was an affair, and he (Mr. Rodriguez) "made his own bed", only a complete idiot and loser ruins the life of his children, his own, as well as countless others over a wayward woman. If she's cheating, you be a man, and you move on. There are countless other good women out there, and seeing your kids every other weekend is a far cry better than never seeing them again and ruining them for life by bringing such violence into their lives.
An azz kicking may have been in order. Exposure and ruining his credibility may have been in order. No good is ever going to come out of killing someone over a chick that knows no loyalty or faithfulness (again, if that was the case here...apparently the husband believed so).
Guns are responsible for killing as much as Rosie O'Donnel's fork is responsible for her being FAT.
