Where are the cast of The Rifleman?

As of my last update, many of the main cast members of "The Rifleman" have passed away. Chuck Connors, who played Lucas McCain, died in 1992, while Johnny Crawford, who portrayed his son Mark, passed away in April 2021. Other cast members, like Paul Fix, who played Marshal Micah Torrance, have also passed. The show aired from 1958 to 1963 and remains a classic, but its primary cast is no longer living.
