How Did Kristoff St. John Die? New Details Young & The Restless Star Death, Overdose, And Son's Suicide

Longtime "The Young & The Restless" star Kristoff St. John has died at age 52.

St. John was found dead on Sunday after a friend found his body in his Woodland Hills home, according to TMZ. Police and paramedics responded to the scene around 2:05 p.m. when the friend called 911 about a possible alcohol overdose. Foul play is not suspected in the actor's death. A source told the outlet that alcohol may have been involved.

"Sadly we can confirm," said his attorney, Mark Geragos, in an email.

The Los Angeles County Department of the Medical Examiner-Coroner Public Information Officer Sarah Ardalani told USA Today that St. Johns was pronounced dead at the scene at 4:02 p.m. An autopsy is scheduled for Monday.

According to TMZ, St. John was treated for depression earlier this month and was released just before his death. A source close to the Y&R star revealed to the outlet that he had checked himself into the UCLA Medical Center in January for depression issues and was recently released. His depression was partially linked to his son's 2014 suicide, the source added.

I am still trying to process the news that this dear, dear man is gone. Forgive me if what I say here doesn’t come together just right, but I have to say something about @kristoffstjohn. He deserves as loving a tribute as my early morning sadness can muster. #KristoffStJohn was love. Just pure and simple: love. He was the kind of person you meet who you feel like you’ve known your entire life. He had a gift for making people feel instantly at ease. He could immediately diffuse any nervousness you had. In my case, I was a ball of nerves because I was playing my first role on a soap opera ever...on #YandR which happened to be one of my FAVORITE soap operas...AND I was meeting HIM, who I had been a fan of most of my life. It could have been a scary, heavy moment. Kristoff made it LIGHT. In my character, Lois’ subsequent visits to Genoa City, Kristoff was more of the same. Kind, encouraging, playful, fun and present. He saw me. He saw EVERYONE. He made time for everyone. He celebrated everyone. No matter who you were. He saw you. We spent our last lunch break together (the day this picture was taken) eating with a background actor who had been sitting alone in the commissary. Not on Kristoff’s watch. He called her over to join us and the three of us had an amazing time. She got to geek out and ask every question she had and she and I both properly fan-girled over the gift of this lovely man. Kristoff made that moment happen. He saw her. More importantly he felt her. He didn’t want her to be alone in a new place. He did the same for me. That is who he was a man. He was just GOOD. I am heartbroken to hear that he is gone. So heartbroken. #RIP dear heart.

St, John played Neil Winters on the famed CBS soap opera since 1991, a role that earned him 10 NAACP Image Awards and nine Daytime Emmy Award nominations.

He also had starred in "Charlie & Company" and appeared in "The Bad News Bears," "Hangin' with Mr. Cooper," "Diagnosis Murder," "Arli$$," "The Jamie Foxx Show," "Martin," "Living Single,"and "The San Pedro Beach Bums."

St. John's life outside of Hollywood rivaled that of a soap opera, riddled with pain and drama.

In 2014, St. John's 24-year-old son Julian took his own life while receiving mental health care at La Casa Psychiatric Health Facility in Long Beach, California. Following their son's death, St. John and his ex-wife, Mia St. John, 52, founded the El Sabor es Poder (Knowledge is Power) Foundation in an effort to battle mental illness.

Three years later, near the anniversary of his son's death, St. John threatened to shoot himself and was placed on a 72-hour hold for a psychiatric evaluation.
