I am very sorry for your loss.
However, this is not a question that is appropriate for our forum nor for the internet in general. You need professional assistance, whether it be lawyer, private investigators, police or all of the above.
I sincerely hope you get the assistance you need, but this is not the place.
Still happily answering to the call-sign Peetza.
