The house address is quite easy to find and Google Maps shows the home to be very humble. I seriously doubt McWhorter makes/made much.
Six kids? Could be. Possibly the victims?
Since when do neighbors know about a guy's inability to have sex? From Steadfast's link above:
"....Neighbors say McWhorter had a medical condition that prevented him from having sex. He couldnt physically rape anyone, said RH, He had physical problems that prevented him from doing that....
One doesn't need the use of their genitalia to rape, after all.
