I think unfortunately he was a too good guy.
Probably naive in a way and easy to manipulate.
He realized the one he was leaving with was really a threat
for his life;
that's why he started to think about filing for divorce and make a Will with the Lawyer, quitting the band and moving far away
That's what I think/
Never too late to re-open the CASE even if he's dead
At least there would be Justice
Someone is enjoying his $ that she doesn't deserve
