IIRC from remarks late last year, DeWine and Reader aren't on the same page when it comes to drug involvement. DeWine thought drugs had something to do with it. Reader seems to go back and forth.
IMO, it's a highly unusual, methodical killing, one that usually only occurs in relation to some kind of organized crime. Perps planned well in advance and managed to remove much of the evidence. IMO, with so many people killed in multiple locations in a couple hours time, with multiple guns, lots of ammo and likely with silencers - these were likely professionals or semi-pros.
With so much drug trading, growing and manufacturing in this area and having violence that moves out into surrounding areas, it's likely some kind of organized crime.
From the first hours, LE has locked down all evidence and information relating to the case. Nearly total media blackout. With the exception of the infants/small children, LE has shown little respect or concern for the victims and their families. They've shown little concern for the safety of the community at large, never making an attempt to meet with citizens they serve to reassure them or offer support. I'm not a pro, but it seems like they could use some outside advice on building a better rapport with the community to get the information they need.
I'm not sure if LE knows who the killers are. The people who know that are dead. LE probably knows who in town might know something about it, and are frustrated they're not talking. Can't say I blame them, they would be putting themselves and their families at risk with no hope of protection from LE if they do talk. Those murders sent a big, loud message to the people in that region, as the killers intended. Anyone who knows anything must not feel safe enough to go to LE with information, or they would have by now. Why are people afraid to talk? That's an important question.
Small town justice can be pretty swift. If it was a disgruntled ex or boyfriend or jealous neighbor/relative who pulled this off, they would have been arrested and charged by now. Crimes of passion usually leave some evidence, poor people can't afford good lawyers and backwoods prosecutors don't usually have to bring forth a mountain of evidence to get the verdict they want from a local jury.
I feel badly for the people who live in that area. I hope this is resolved soon, but I'm not sure it will be. I still wish outside LE pros were in charge.
