Andrew Koenig The search continues for 'Growing Pains' actor Andrew Koenig. Now his famous father, Walter Koenig, is opening up about the painful search for his missing son. "It's very, very tough," the elder Koenig, who starred on 'Star Trek,' tells the 'Today Show.' "He was very depressed about his life."

Koenig, best known for playing "Boner" on 'Growing Pains,' went missing in Vancouver a week ago.

His mother, Judy Levitt Koenig, hopes that the public's concern brings him home. "He is much loved and beloved in this world and I just hope he gets that feeling," she says.
