TUCSON (KGUN9-TV) - The record heat has Sheriff's Deputies searching for a 33 year old German man missing on Ventana Canyon Trail.
Crews resumed the search Tuesday morning with added help from Pinal County Sheriff's Department.
Marcus Turowski is a visitor from Germany. He and two other German tourists started up the trail Sunday morning.
57 year old Stefan Guenster was found dead on the trail. Another member of the group survived.
18 year old Adrienna Rasmussen died while hiking on the Finger Rock Trail.
54 Year old Jana Kirkpatrick died yesterday on the Loop trail near Irvington and I-10. She had been walking about 3pm.
Early Monday afternoon, Sheriff Chris Nanos suspended the search for the missing German hiker to protect searchers from the heat. They planned to resume early Tuesday evening.
The Sheriff says stay indoors no matter what time of day.
The search has included deputies,border patrol agents, state troopers, and numerous volunteers.
By early afternoon, Sheriff Chris Nanos decided the extreme heat was a danger to the searchers so he ordered them back until temps back off at the end of the day.
With the exception of the woman who died at about 3pm walking on the Loop near I-10, the hikers took the common advice of setting out early in the morning. They still got in deadly trouble.
Now the sheriff is urging people to stay inside no matter what time it is.
"Get your exercise in your living room. Go to a gym. Do any number of things but don't get outside."
Dr. Michelle Manos of the Pima County Health Department says over the weekend at least two heat victims came to hospitals by ambulance and many more brought themselves in.
She says, “There comes a point when the weather is beyond all preparation, really. We get to the point where the human body is really not made to suffer through these very levels of very very low humidity, very very high temperatures and this beating sun we're all feeling right now."
The missing man has been in those conditions for a day and a half. We asked Lt. Steve Carpenter, the head of the Sheriff's Search and Rescue what chance the man may have.
"Human beings have been known to amaze people with acts of strength and endurance so I can't really say because I don't know the gentleman we're looking for. We'd like to keep our hopes up and we will work this call as hard as we can for as long as we're able to."
It's easy to assume nearly all hikers who get in trouble are out of towners unfamiliar with conditions here.
All three hikers who died Sunday were visitors but the Sheriff and the Health Department say more than 80 percent of heat illnesses happen to locals.
