Actor Alan Thicke offers up his condolences to the family of his "Growing Pains" costar Andrew Koenig, following his tragic death.

Thicke said of his costar, "Andrew's light shone brightly on the 'Growing Pains' set. His skill and humor and friendship were important elements in our extended family. May his own family now find comfort in their memories of the good times with this very special young man."

Koenig's body was found Thursday in a Vancouver park. His parents said in a press conference later that day that their son had committed suicide. The Vancouver Police Department tells ET that there's no foul play suspected in Koenig's death and that the investigation has been turned over to the British Columbia Coroner's Service.
