LOS ANGELES

Kristoff St. John, who played the struggling alcoholic and ladies’ man Neil Winters for 27 years on “The Young and the Restless,” has died. He was 52.

Los Angeles police were called to his home Sunday, Feb. 3, and his body was turned over to the coroner. The cause of death was not immediately available.

Mr. St. John had played Neil Winters on the CBS soap opera since 1991, earning nine daytime Emmy nominations. He won a Daytime Emmy in 1992 for outstanding younger actor in a drama series and won 10 NAACP Image Awards.

His businessman character wended his way through romances, deaths of loved ones and other daytime travails that descended into alcoholism until going into rehab.

Mr. St. John announced in September that he was engaged to model Kseniya Mikhaleva.

“So early.....so early,” she wrote in her Instagram Stories. “Why you are leave so early????Why...you are always in my heart.”

Mr. St. John was twice married and divorced and was the father of a son and two daughters. His 24-year-old son, Julian, committed suicide in 2014.

On Jan. 21, Mr. St. John retweeted “Grieving the loss of a child is a process. It begins on the day your child passes, and ends the day the parent joins them.”

CBS and Sony Pictures Television said in a joint statement that Mr. St. John’s death is heartbreaking.

“He was a very talented actor and an even better person. For those of us who were fortunate enough to work with him on ‘The Young and the Restless’ for the last 27 years, he was a beloved friend whose smile and infectious laugh made every day on set a joy and made audiences love him,” the statement said.

Fellow cast members and friends were shocked and saddened.

“Sitting by myself in my car! It’s raining outside, with dark clouds and wind outside... am reading your tweets about my friend KRISTOFF! Thank you all for your kind words! I have none right now! He was a hell of an actor and simply one of the nicest guys ever! Can’t believe it!” tweeted Eric Braeden, who plays Victor Newman on the show.

Viola Davis and Yvette Nicole Brown were among others. Ms. Brown tweeted: “No!!! This news has truly broken my heart. Kristoff was pure & so kind. I will never forget how wonderful he was to me and everyone else he came into contact with. He was just a good, good man.”
