COLTON, Wash. -- Search and rescue crews in Whitman County will resume their search Monday morning for a Colton High School teacher who has been missing since Saturday morning, when he left for a hunting trip.

Emergency crews from all over the region spent the daylight hours Saturday and Sunday searching for 45-year-old Glen Voshell, who never reported back from a hunting trip in the canyons around Colton.

Many volunteers and Voshell's family joined deputies from Whitman and Latah counties to help search for Voshell, who was supposed to return from a hunting trip Saturday night. The search went to the air, as helicopters were brought in from both the U.S. Border Patrol and the Spokane County Sheriff's Office to help look for Voshell.

The search focused in a 8-mile square area near where friend found Voshell's truck by some canyons off Rimrock Road, in an area west of Colton, between the town and the Snake River.

Voshell's family says he knows the area well, his daughter Kirsi says her father has taken her on many hunting trips in the area. They plan to search for him as long as it takes to find him alive.

"I know he wouldn't leave me out there and I just really want to find him," said Kirsi. "I'm worried that it's been so long and I feel like if we give him another night out there, it's not going to be good."

The Colton area received about four inches of snow on Saturday, but deputies say most of it fell after Voshell and his dog left his truck, burying any tracks beneath the snow.

Deputies suspended the search for the night because of worries that some of the rescuers would get lost in the dark. But Kirsi, her brother and some of their friends say they've packed gear and supplies to launch an all-night search of their own.
