How did he become a millionaire? Having a work history with the US postal service and the IRS doesn’t seem to be the answer. There is something very weird about this story of him and his “girlfriend,” who is married to two men.
I’ve read that he made real estate investments.
His career and hobbies suggest both statistical and logistical idiot-savant capabilities. Autistic? for the absence of online presence and standoffishness? His dad’s friends who influenced him growing weren’t exactly pillars of the community.
