Authorities will resume the search for a Canadian man who went missing in March in Nevada's high desert mountains.

Albert Chretien, 59, of Penticton, British Columbia, was en route to a tradeshow in Las Vegas with his wife, Rita, 56, when the couple took a few wrong turns and their van got stuck March 19 in an isolated area near Mountain City, Nevada. The Chretiens, who attend the Penticton Church of the Nazarene, decided to wait for help inside the van.

After three days, Albert Chretien went for help using a GPS device and Rita Chretien remained in the van. Hunters found Rita 49 days later. She had survived on handfuls of trail mix, candy, and water. 

Rita Chretien, who lost 30 pounds in the ordeal, was treated at an Idaho hospital and then transferred to a medical facility in Penticton. She is now home.

Rescue teams with the Elko County Sheriff's Office searched an entire week for Albert after Rita Chretien was found, but weather and packed snow forced authorities to postpone the search until conditions improved.

The sheriff's office said Tuesday a new search will focus on an area called Telephone Creek Road. Authorities think Albert Chretien might have followed telephone lines in hopes of finding a residence. Although it's unlikely Chretien is alive, authorities will continue to search until they find him, giving the family some closure, a sheriff's spokesperson said.
