I have a hard time believing that either robbery would be a motive for killing 8 people - if Chris kept large amounts of money at his house, I understand how he could wind up being killed, and maybe his wife (he was shot 9 times, with 2 in the head, and she was shot twice in the head as she slept). But then why take a chance getting caught murdering everyone else? I also do not believe there was enough Cannabis for the Cartels to get involved. No, instead, I find it ironic that in that small town, these guys could be selling right under the nose of Law Enforcement... I lived in a small town where I was a LEO, and we knew EVERYONE who was dealing - it was just a matter of catching them. I think these killings were done so incredibly well that whomever the subjects are, they clearly had a strong grasp of evidence collection, and what the Police would be looking for. Tire tracks outside? Footprints in the grass? Why did they lock the door behind them? How did they get in without anyone noticing? I get a feeling that the UnSub(S) are LEO's as well, who were involved with Cannabis distribution. LEO's would have a real hard time shooting babies - the Cartel would not. I believe Chris may have threatened to report them, and they hit back.
