The Sacramento Metropolitan Fire District has concluded that it could find no evidence that a person was injured or killed where a hillside collapsed along the American River bluffs east of the Fair Oaks Bridge.
At noon, Sac Metro fire officials said that "based on neither of the two human remains dogs finding anything" the department's responders "have terminated command and concluded search operations."
The agency had sent about 20 firefighters back to check the area Sunday morning after a half dozen people reported seeing a shirtless man in black short who was hiking in the area Saturday evening disappear.
He was walking on the north side of the American River when the hillside collapsed.
Based on those reports, Sac Metro Fire reported deploying about 60 people, using search dogs, boats and helicopers on Saturday night.
Fire Captain Bryan Thomson at 10 p.m. Saturday said: "Our heavy rescue crew is digging off 15 yards of dirt by hand in a very precarious place."
He said it isn't uncommon in the area for dirt to give way. "We had the same thing a week ago just upstream of the Fair Oaks Bridge and we rescued a guy from the side of the cliff. There's a little dirt path, you go straight up like a billy goat or a deer, but we get people who try to crawl on it."
