He was written out of the show during the second season. They didn't really give a reason, other than they wanted to open up parts for other characters.
The guy who played him is 77 years old. When he disappeared from the show, I honestly thought he'd died, but when I checked his IMDB listing, it didn't have a date of death.
My guess is that Douglas Fisher wanted to pursue other things, so he left the show.
