May 24, 2021 Officials who have been searching for a Cottonwood man missing since a boating accident on the Salmon River Saturday are now considering “a worst-case scenario,” Idaho County Chief Deputy Brian Hewson said Monday. More than 70 people from multiple agencies and other volunteers scoured the river, banks and hillsides about 2 miles upstream from the Pine Bar Recreation Area on the Salmon River looking for David Spencer, 31. Spencer had been in a 16-foot Bass Master boat fishing with his brother, Peter, Saturday, when the boat flipped in the water and sank immediately, Hewson said. Peter Spencer made it to shore but David Spencer has not been seen since. He was wearing black clothing but was not wearing a life jacket, the sheriff’s office reported.
