TUCSON - Search and rescue teams continue the search for a 54-year-old man from Texas who went missing while hiking in Mt. Lemmon.
Scott Bertrand did not return on schedule after he went on a hike Thursday morning.
Search and rescue crews from the Pima County Sheriff's Department worked with the all-volunteer Southern Arizona Rescue Association to launch a full-scale search, including volunteers, canines and two helicopters.
Law enforcement used GPS data from Bertrand's phone to get a better picture of where to locate him.
However, at some point Friday, deputies "did not receive any further GPS coordinates from the phone" and believe the battery is dead or the phone is off.
Bertrand's car was located near the Green Mountain trail but the search includes a large area with tough terrain.
"This is just a real challenging area," said Mike Jennings, a volunteer member with SARA. "The primary search right now is quite a ways out, so it's just a lot of work to get out to the search area."
Weather has also become a factor for some volunteers as they have been forced to deal with rain and hail from recent storms.
"Time is always going to be a factor and one of the things that we pay attention to closely, mainly because we don't know how prepared he really was for this hike," said Deputy Jesus Banuelos.
Bertrand's wife told deputies that while she is worried, she full-heartedly believes her husband is a fighter and will be okay.
Search and rescue crews suspended the search Saturday evening as they planned how to tackle the efforts early Sunday morning.
