I am simply having a brainstorm her and NOT advocating or suggesting someone do something illegal.
The issue must be resolved!! Legal action has, to date, failed. Many folks are becoming more frustrated. Just Sayin.
A much better (and easier) option is to get his college records.
There is a reason they have not been released, and I don’t think it’s grades.
He’s almost certainly listed as an international student, probably Indonesian, and probably on scholarship.
Maybe even copies of the BC there.
There are surely plenty of people at Occidental, Columbia, Harvard, with access.
