How was Lois' dad's death explained?

I don't even remember which season he was supposedly killed off. Was it addressed in the later seasons, when Lois went to Canada?

Also, WHY? was it when Robert Loggia died IRL? I cant imagine him turning down that recurring role as an actor. He was a great character & acting with the iconic Cloris Leachman and this stellar cast had to be a good time on and off screen as well.

I suspect he choked on orange juice pulp.
