PHOENIX -- Triple-digit temperatures shortened the search for a man from Washington state who's believed missing while hiking a Phoenix mountain.
Phoenix police said crews had to stop the search Monday for 23-year-old Eric Fernandes because of 110-degree conditions.
Fernandes and his father were in the visiting friends. After having lunch with his father and friends Saturday, Fernandes went hiking alone.
He has not been seen or heard from since. His father reported him missing Sunday, and shortly thereafter his vehicle was found at the Echo Canyon trailhead.
Temperatures reached 108 degrees Saturday and an excessive heat warning was issued for Monday, when the high hit 110 degrees.
The search was scheduled to resume Tuesday morning.
Investigators left a poster with Fernandes' photo and other information on the Camelback Mountain trailheads.
Police are searching for the person who was last seen with Fernandes at a local sporting goods store about 1:30 p.m.
