I read at another website that Seth was gay and his family would rather he stay in the closet, even when deceased.
And IMHO, I would bet that somebody somewhere has pictures or a video of him having gay-fun; it is certainly within the realm of DC possibilities.
So- I’m not saying this is what happened- but the family were already embarrassed about his alternate lifestyle and would never want any proof of that made public.
This explains why they remain silent -—> AND I also wouldn’t be surprised if they had to make a “donation” -or $everal- to a red ribbon/rainbow charity....because it would be good for their “health”.
If his family are big time libs, they ought to be proud to have a gay son.
So his girlfriend was just a cover?
