Search and rescue crews in Sublette County completed the day’s sonar scan north of Moosehead Bay in Fremont Lake but were unsuccessful in finding the body of Rick De Ruiter Zylker, who was last seen on Wednesday afternoon while swimming with friends and co-workers.
The search crew is using its readings to build a 3D sonar map showing the steep sides and cliff sections of the lake bottom which will assist volunteers with the use of a remote operated underwater vehicle.
Two search dog teams from Driggs, Idaho and Jackson, were deployed today to conduct a free air sniff search of the water and shoreline.
Both dog teams indicated scent from the water.
The search will resume tomorrow with tightened search pattern.
