A man is missing in Ventana Canyon after hiking in the extreme heat on Sunday.
Search and Rescue and the Pima County Sheriff's Department led the search effort with help from a Border Patrol K-9 unit and an air unit.
The department suspended the search mid-day Monday due to safety concerns caused by the heat. PCSD is advising everyone to stay inside as temperatures climb above 110 degrees.
The missing man was hiking with two other people and was last heard from around 11 a.m. Sunday, according to the Pima County Sheriff's Department. One of the men he was with was able to make it back to the trail head, but the other hiker he was with was found dead. The group was reported by a passerby who said the men looked dehydrated in the extreme heat.
The Sheriff's Department has identified the man that is still missing as 33-year-old Marcus Turowski who is from Germany. The department is asking for the public's help in finding Turowski.
He is described as Caucasian with a thin build and blonde hair. He was last seen wearing a green shirt and jean shorts.
Sheriff's deputies identified the man who died while hiking with Turowski as 57-year-old Stefan Guenster. Deputies found him deceased near the trail.
This was one of three major search and rescue efforts for a total of seven missing hikers in Pima County Sunday because of the extreme heat.
Some groups are calling for a law that fines hikers who need to get rescued, like the "Stupid Motorist Law," but the Mountain Rescue Association said in a statement that that will only stop people from calling 911 in the first place.
"No one should ever be made to feel they must delay in notifying the proper authorities of a search or rescue incident out of fear of possible charges. The expert volunteer teams of MRA are proud to be able to provide search and rescue at NO cost and have NO plans to charge in the future."
The Southern Arizona Rescue Association is advising everyone to stay inside and avoid all outdoor activities after 10 a.m. If you do want to go for a hike or exercise outside, go early, and make sure to turn back once your water is halfway gone.
