Members of Coquitlam Search and Rescue (SAR) are off to help find a missing U.S. man in the B.C. Interior.

Warren Andrew Sill, 26, has not been seen since July 5, when he parked his car at the entrance of Whiskey Creek Trail, 80 kilometres northeast of Terrace. On Monday, five Coquitlam SAR members flew up to the area to help with the search.

It's expected the team will be involved in the search until the weekend. Sill, who is from Ohio, went missing while making a documentary on B.C.'s endangered Spirit Bear.

Jim Delgrande, a Coquitlam SAR manager, explained the members will be helping out with various tasks during their trip, from routine searches of forest and undergrowth areas to potentially using their skills for rope and swiftwater rescue. "We're a large team and we have a very wide skill set," he said, adding the unit was more than willing to help after being asked.

Delgrande noted for a big search like the one in Terrace, it's not unusual for Coquitlam SAR to be called in to help. With about 50 active members, he said the loss of five to Terrace wouldn't have an effect on any potential rescue locally.
