Koenig's parents plead for son to contact them

The parents of missing "Growing Pains" actor Andrew Koenig have issued an emotional plea for their son to contact them.

"I just want to know you're OK," Walter Koenig said in the appeal. "If it means you just want to stay here, that's OK. You don't have to come back. Just let us know that's your intention."

Koenig was visiting friends in Vancouver when he went missing more than a week ago, The Associated Press reports.

The Venice, Calif., native had a recurring role on the 1980s sitcom as Boner, a pal of star Kirk Cameron's character, Mike.

Walter Koenig, best known for playing Pavel Chekov on the original "Star Trek" television series, said yesterday his son stopped taking antidepressant medication about a year ago.

Vancouver police Constable Tim Fanning says there has been no activity on Koenig's cell phone or bank records since Feb. 16.
