Yes, yes they did. Very gray. Not that I'm fond of the pot farm title, but most folks just wanting to ensure their kids got a good Christmas, can do so with much fewer then 200 plants, if that figure is correct. Let's be real. Five to fifteen tops, and that's a pretty good haul. The Rs were making pretty decent $, off of a couple hundred, but weren't raising enough to hoist lots of red flags.
However, if a former girlfriend, and all of her family dies, and the suspects had an illegal silencer, and the "fluff" from said silencer matched that at the scenes of the deceased, I'm going to give it a lot more leverage, especially since there is no way they'd have had that silencer legally . They built it on their own, with those materials, materials likely found on the persons of the deceased, too, namely, GR who even had a muzzle stamp on his temple.
