Worst murder plan or time-traveling idiot?

Tore Nielsen notes that a tv series about this bizarre murder case would be unethical. I’m just marveling at the #gameable possibilities.
Man crowdfunds and builds own submarine.
Journalist goes aboard, disappears.
Bits of journalist are found, it looks bad for submariner man.
….so if you wanted to kill a person, this would be the most traceable, least smart way to do it. If you can’t keep your story straight afterwards, it really looks damning.
So that’s merely crazy and tragic. But (here’s the gameable bit) what if he’s innocent?
What if there’s a rational explanation that is not the obvious?

Bonus points for no Call of Cthulhu – remember, we’re avoiding the obvious.

But. He goes into an elevator alive. Doors open: dead.
I see a GURPS Time Travel/Alternate Earths adventure, at least. Possible Time Lord involvement? Multiple Prince coccoons? Did we let our subscription lapse?
So very very #gameable guys.
