Andrew Koenig may not be a household name, but odds are he has graced your TV screens over the years.
Unfortunately, the 41-year-old former Growing Pains star has been missing nearly a week and friends and family members are asking for help in finding their loved one.
His father, Star Trek star Walter "Chekov" Koenig, has dedicated his site to finding his son, noting he last heard from Andrew on Feb. 9. Andrew, who suffers from depression, was last seen by friends in Vancouver on Feb. 14. He was supposed to catch a flight back to the U.S. on the 16th, but never made it. Since then, the family has alerted local authorities.
The elder Koenig says Vancouver police "have been kind, sensitive, generous and just extraordinary...Their investigators are working tirelessly."
Constable Jana McGuinness, a spokeswoman for the Vancouver Police Department, tells E! News, "So far there are no new details, but we are hoping someone will see this and call us with new information."
During his time in Vancouver, Koenig stayed with burlesque dancer and friend Jenny Magenta.
"His parents have contacted us as he hasn't arrived and they have evidence that he his severely depressed," Magenta explained in a Facebook message late Friday afternoon.
"Lots of people are looking. And say some prayers or think some positive thoughts?" television host Dave Holmes adds on the site MaximumFun.
The Twitterverse is also abuzz with news of the missing Koenig, including tweets requesting for any knowledge of his whereabouts from Sarah Silverman, Alyssa Milano, Kevin Smith and comedian Doug Benson.
Best known for his role as Mike Seaver's (Kirk Cameron) best friend, Richard "Boner" Stabone, on Growing Pains, Koenig made headlines back in 2008 after protesting a controversial float in Pasadena's Rose Parade. This "act of civil disobedience" stemmed from his work with human rights group U.S. Campaign for Burma over the years, alongside his father.
The younger Koenig, who also appeared on Star Trek: Deep Space Nine, currently works as video producer on the podcast Not Never Funny.
