New Mexico State Police said Friday that they have no leads yet on 61-year-old Walter Scheib, the White House chef for 11 years under Presidents Bill Clinton and George W. Bush.
Scheib recently moved from Florida to Taos, New Mexico, and reportedly went for a hike last Saturday in the mountains near the Taos Ski Valley.
His girlfriend reported him missing, and police found his car Tuesday parked at the Yerba Canyon trailhead.
Authorities are using search-and-rescue dogs and helicopters to view areas too rough and remote to reach on foot.
The U.S. Air Force and the New Mexico National Guard are assisting in the search.
