A former high level DEA guy thinks it was Mexican Cartels.
I think it was either Mexicans or domestic bike gang druggies (this is on the border with Kentucky, which has a lot of both). They were apparently also doing cockfighting, which in my state can be black or rural white as well as Mexican (we don’t have a lot of Mexicans here). Seems this family was dealing with some seriously bad actors.
One of my son’s friends when he was a teenager - a boy from a ‘”good Motmon family” - was shot to death on a back road near our town in California because kids don’t realize exactly how serious this is and what they’re dealing with. But on the other hand, the adults in his family weren’t doing grow houses and building tents (cockfighting) as this family appears to have been doing.
