Kristoff St. John, one of the stars of the long-running soap opera "Young and the Restless", was found dead on Sunday. He was 52.

According to TMZ, one of Kristoff's friends went to check on him at his home in San Fernando Valley, California and found his body. Paramedics and police were called but he was pronounced dead on the scene.

There was reportedly no sign of foul play, but one source says alcohol might have been a factor.

Kristoff has played the role of Neil Winters on "Y&R" since 1991. He's garnered nine Daytime Emmy Award nominations. He also won 10 NAACP Image Awards.

Unfortunately, Kristoff and his family have seen tragedy in the past. He and his ex-wife, boxer Mia St. John, lost a son back in 2014 when he took his own life.

And in 2017, around the anniversary of his son's death, Kristoff threatened to kill himself with a gun. Cops put him under a 72-hour hold for psychiatric evaluation.
