Thjey just said on the lastest press conf that they were not able to usee the horses or dogs due to the terrain.
And that they have tracked him to the Rouge River.
Apparently he left the logging road for the creek and that this creek is too steep for horses ( hundred foot cliffs, etc ).
The sheriff also said that they were bringing a special team in from Eugene who is equiped for cold water searches...sounds bad.
He also said that a specialized 'man' searcher was in route from Bend...
Rogue River. Trust me on this one.
