The Honolulu Star or whatever the newspaper in Hawaii did a timeline on when he flew over a few days before she supposedly died. It showed he spent all of about a half hour (don't remember the exact number of minutes but it's on FR somewhere) visiting in her apartment and then headed to the golf course. You know, just long enough to rummage through the closet his book claimed the BC was in. Doesn't everyone fly a few thousand miles to see their grandma for the last time and only spend moments with her because you have to make your tee time?
Then she coincidentally died. Some speculate she died 3 days earlier than her death certificate says. Either way, she was cremated and dumped into the ocean so no one will ever find out the truth. Notice Moo and the girls stayed here so they wouldn't be witnesses.
So he made contact with her?
Probably just a coincidence. Again.
