The hunt for John V. Zazzara, 54, was suspended late Friday, Klamath County Sheriff Tim Evinger said in a news release.

"It is very difficult to make the decision to scale back any search before a missing person has been found," Evinger said. "In this instance, little is known about (Zazzara’s) intended whereabouts and how he was prepared for his outing. In this case, time and conditions were not in our favor."

Approximately 30 searchers from Klamath and Jackson counties scoured much of Mount McLoughlin on Thursday and Friday. The 9,495-foot summit remained shrouded in clouds and blowing snow throughout the two-day search, Evinger said.

Efforts to find Zazzara may continue when the weather improves, Evinger said.

Search teams traveled to the mountain on Thursday, after a friend reported Zazzara as missing.

His Toyota sport-utility vehicle was found later Thursday parked at a trailhead on the east side of the mountain in Klamath County. Police removed the vehicle from the area on Friday, officials said.
