R.I.P.: Mark Landon (1948-2009)

C&I offers condolences to the friends and family of Mark Landon, son of Bonanza and Little House on the Prairie star Michael Landon, who was found dead Monday in his Hollywood home at age 60. (According to published reports, the L.A. County Sheriff's Department is investigating the incident, though a police spokesperson has said there was no evidence of foul play.) As an actor, Mark appeared in three TV-movies during the 1990s, most notably Us (1991), the final project written and directed by and starring his father before Michael's death of cancer in 1991.
