Gretta had 2 shows covering this story shortly after Ray Gricar disappeared along with former homicide detective Ted Williams.
After watching the first of the 2, where she visited the mini-mall in Lewisburg near the antique store where his car was parked, and walked down the path to the river, I was left with the impression that there may well be a homosexual link.
No hard evidence, just a feeling I took away from the show.
Riverbanks do tend to attract homosexuals. And the antique store is literally a stone's throw from the Susquehanna.
I live near Lewisburg, the home town of Bucknell U., and yes, it is a favorite hangout for older, affluent gays.
