I agree, and that's what I had in mind (although not expressed as well as you did) when I typed my "routine move" comment. IOW, "home in a trust" isn't useful as an indicator of much anything beyond having average legal advice with structuring ones assets. Said another way, I think "house is in a trust" is irrelevant.
Assuming arguendo that this was a suicide, it was necessarily premeditated to some extent. Suicide, without more, implies premeditation.
Legal zoomers think alike.
