In any case, get more detail on this "living off the grid" thing. According to who?

This is a good one to pursue. There's more than what we know right now and probing is the way to go.

when Keating was a kid.
It seems that way, but that's sort of my point. How could his neighbors (and the local police?) know, but not the NSC?

Important to mention that military often call someone a kid when they're fresh into military.
However given how long it's been he's likely just 40's unless we can get his official age.
Towns gossip, but I entirely agree. The NSC probably has better intel on the matter, but the past is the past for now.

>previous criminal records
>What is the weapon murder?
>Check for any surveillance device that might have captured the suspect or the act.

The point of living off the grid is so that nobody knows. Not everyone who commits a crime has it on their record, and he's likely done everything he can to avoid being found out, if he'd done anything prior.
Furthermore the description seemed blunt trauma or gunshot, and that needs further investigation. Time of death, method, if any fingernails have been found.
Surveillance wasn't uncommon, but you aren't going to find anything for a house that's on sale like this. The best we can hope for is CCTV from nearby convenience stores, but that takes time to analyze, and he's likely avoided them religiously if he's been off the grid.

Some understanding of the couple's relationship would be good. How much did she know of her husband's past?

Agreed.

>Check for signs of a struggle. Any bruising on the arms or wrists?
>Ask if any traces of communication between the suspect and the victims has been found.
>Signs of forced entry?
>Triple homicide. Seen bodies 1&2, check upstairs for body #3.

It went like an execution. They likely didn't struggle. There's potential that this killing was to silence them. Motive likely goes along the same lines as to: ('execution', positioning of the bodies, how they were left that way, fingernails)
Agreed
Unlikely, but we should ask.
>Sounds like a nuclear family, so #3 is either the other spouse.

My theory is that if this is Keating's family he likely killed them to cover things up. If this isn't his family and just one that got the unlucky draw, then there's still more to this we don't know.
