Tenuous link but looks like the two boys in photos with parents were special, and the lady in the second case was in special education. In a small town they could have been part of the same support group.
A scenario:
Brooks is abusive towards his son, the cop in the first case finds out from the teacher in the second case and confronts Brooks. Brooks and his brother Nick kill the cop in the ambush.
Next, teacher starts to put things together. After her home security is tested (see her facebook post) she's killed, daughter is collateral damage, car used is Brooks' wife's (notice the similarities between the two vehicles).
Brook's wife, Crystal is now getting suspicious of her husband. She disappears.
Crystal's father is starting to put things together, questioning Crystal's 10 year-old son in private, away from Brooks, under the pretense of a hunting trip. He's assassinated.

I was a tenant of theirs. Brooks wasn't mean to Eli. At least I've never heard anyone, even people that hate him, say that. Officer Ellis was doing some kind of internal investigation and was allegedly supposed to meet with internal affairs that monday.
I think Ellis was investigating drugs. A police officer in Bullitt county, which is the next town over, was caught going to Mexico and bringing drugs back. He was on tape and when they asked him if he was afraid other cops would get him he said they're making too much money. If they do, we'll get rid of them we've done it before. Although the story on him was deleted from the online newspaper the next day.
His last name was Matringly. His relative worked for Bardstown or Nelson county. He'd killed a teenager in Louisville. Then had a couple of kills in Nelson. Including a suicidal man that he goaded on and told him to do it, that he didn't have all day. He was formerly a sharpshooter.
That doesn't mean that maybe brooks and nick weren't somehow connected. A neighbor claims that brooks said he'd been trying to break up with crystal but she was blackmailing him. Idk if that's true or not. But brooks is by no means a genius.
If he did do something to her i'd bet that it was one of their fights gone too far. And he called nick for the coverup. Nick claims that the hair they found in his trunk was from her hairbrush. That they'd gone swimming and she put her things in the trunk of his police cruiser.
