An extensive search is underway in northwestern British Columbia for a missing Prince Rupert man.

Adam Moore, 26, was reported missing on Tuesday, the RCMP told reporters at a news conference.

He was last seen near a local 7-Eleven store on Sunday, Dec. 29 at about 3:15 a.m. PT.

There have been reports Moore may have driven to Terrace, but police have been unable to confirm that.

RCMP, CN Rail police and Royal Canadian Marine Search and Rescue are searching the area between Prince Rupert and Terrace. A coast guard helicopter is expected to join the search.

Moore is described at six feet tall with a slim build. He has short brown hair and brown eyes. He drives a black 2005 Volkswagen Jetta with B.C. licence plate number 517 NVV.

Prince Rupert RCMP Const. Matt Ericson said anyone with information should contact police.

"As we continue in this search effort we are appealing to Prince Rupert and the surrounding community for any possible leads that could assist us in finding Adam," Ericson said in a written statement.

"Something that the public may feel is insignificant may be imperative to our investigation and we are urging the public to make contact with investigators," he said.
