Gilbert firefighters late Wednesday rescued a naked man who had climbed down a 40-foot sewer hole.

Police later cited Eugene Gimzelberg, 32, of Gilbert, for trespassing and criminal damage after he told them he had gone down the hole after smoking PCP and marijuana and consuming mushrooms a day earlier.

A rescue was sent out around 11:40 p.m. after two passersby reported they heard someone screaming for help in a west Higley field north of Loop 202.

They found Gimzelberg, naked except for one shoe, alert and able to communicate, although he sustained major injuries from the fall.

Rescuers made sure that Gimzelberg had a good supply of oxygen during the rescue, and that within an hour of the 911 call, a firefighter was hooked up to a harness and sent down into the hole to get him, Gilbert Fire Department spokesman Mike Connor.

Upon his rescue, Gimzelberg admitted to police that he had been smoking PCP and marijuana as well as consuming mushrooms on Tuesday, according to a report by police Sgt. William Balafas.

Balafas said that police had received a call Tuesday about a man behaving suspiciously, emptying the contents of his wallet onto the ground while yelling and running around the neighborhood in the area of Agritopia Loop near Ray Road and Loop 202.

At the time of the call, Gimzelberg was reported to still be wearing clothes, Balafas said.

Police do not know the exact time that Gimzelberg climbed down into the manhole, but family members reported that before his rescue Gimzelberg was last seen Tuesday morning.

Gimzelberg told police that he was high and climbed into the drain to get away from officers.

Gimzelberg was later transported to Scottsdale HealthCare Medical Center, where he was treated for multiple skull fractures and lung injuries. He is listed in critical but stable condition.
