Michael Landon's eldest son dead

Mark Landon, an actor and eldest son of "Little House on the Prairie" star Michael Landon, was found dead Monday at his home. He was 60.

He was found about noon in the 1300 block of Sweetzer Avenue.

The cause of death was not immediately clear but there was no evidence of foul play, said Sgt. David Infante of the Los Angeles County sheriff's office.

The Los Angeles County Sheriff's Department is investigating the incident, but a spokeswoman said there was no evidence of foul play.

Michael Landon, one of the stars of “Bonanza” and “Little House on the Prairie” television series, died in 1991 of cancer.

Mark Landon, among Michael Landon's nine children, appeared in three movies, including "Us" - a CBS television movie written and directed by his father in 1991 just before he died of cancer at age 54. The film was a pilot intended to be another series for Michael Landon. It aired a few months after his death.
