One of the all-time great TV dads, Alan Thicke, has died at the age of 69. Thicke, a massive hockey fan who often played in charity games with legends of the sport and other celebrities, was reportedly playing hockey with his son when he suffered a heart attack and was taken to Providence St. Joseph’s Medical Center where he later passed away.

Thicke is best known for playing Dr. Jason Seaver on the hit ABC sitcom Growing Pains. The show ran for 167 episodes from 1985 to 1992, and also starred Joanna Kearns as Thicke’s character’s wife, and Kirk Cameron, Tracey Gold, and Jeremy Miller as the character’s children, with Ashley Johnson playing the suddenly much older youngest child for the last couple of seasons. A homeless teenager (played by Leonardo DiCaprio) was brought into the family during the show’s final season.

Earlier last week, close friends and fans of actor Andrew Koenig took over popular sites like Twitter asking people to keep their eyes open for Koenig, who had recently gone missing in Vancouver, where he was said to be visiting friends. Sadly, the actor’s body was found today in one of his favorite places to go while in Canada, Stanley Park, where he had committed suicide. He was 41 years old.

Many had expressed their worry for Koenig after his disappearance on Valentine’s Day due to a history of depression and difficulties with life, and in those instances, this is always the worst case scenario.

Koenig was best known as for his role as Richard “Boner” Stabone, Kirk Cameron’s best friend on the 80s TV series Growing Pains. He also appeared on shows like My Two Dads and Star Trek: Deep Space Nine. His stint on Star Trek was fitting as his father, Walter Koenig, played Chekov on the original series with William Shatner. The father and son appeared together in a film called InAlienable in 2008. The actor, who was also a writer and producer, also did voice work for cartoon series like G.I. Joe and appeared as The Joker in Batman: Dead End, a fan-made film.
