Search and rescue crews scoured Stanley Park Tuesday for a California man who's been missing for a week.

Andrew Koenig, best known for playing the role of Boner on the television sitcom "Growing Pains," arrived in Vancouver on Feb. 11 to spend a few days with some friends.

A woman with whom Koenig had been staying told CTV News Tuesday night Koenig wasn't his usual self during his visit, appearing more quiet and reserved.

The woman, a burlesque dancer who would only identify herself by her stage name Jenny Magenta, said that Koenig had originally planned on staying for three nights but then asked to stay an extra night.

They had spent Valentine's Day hanging out and reminiscing about good times, she said.

The following day, Koenig left behind a quick thank-you note when Magenta was out of the house.

"It's weird he didn't give us a quick call," she said.

Then, a couple days later, police came to her home. She learned that Koenig's parents had received a disturbing email from him, prompting them to call authorities.

Vancouver police said Tuesday that there has been no activity on Koenig's cell phone or bank records since Feb. 16, when he was last seen in south Vancouver.

"Police are still hopeful that Andrew will be found alive and safe," they said in a statement.

Koenig's family arrived in Vancouver Tuesday to help with the search.

The search concentrated in Stanley Park because Koenig loved nature and enjoyed walking in the park, Magenta said. Authorities also picked up a signal from his cell phone in that general location, she said.

"It's just now turning into something that's just confusing, tragic and sad. We just don't know a lot."
