I was leaning towards the cousins as having hired someone.
With what I've seen on the internet about their international connections to other world leaders. I'm leaning towards way higher up the power chain although I have no definitive proof.

You also all know that garage doors with a code can be opened with a remote. People drive by homes with these coded garages all the time with remotes to see if they will open.
At my day job, people give me their access codes . Please change your codes regularly, especially after a home service.
This was IMO. No suicide, no suicide-murder. Just plain murder.
