The second full day of searching for two missing Coeur d'Alene men in the Riggins area came up empty on Tuesday.

Two neighbors - Patrick Lusk, 27, and Jason Gritten, 35 - hadn't been found as of press time Tuesday night.

The two went to the French Creek area of the Salmon River about 15 miles east of Riggins to hunt bear over the weekend. They were reported missing on Sunday at 7:15 p.m. when no one had heard from them.

"We have found their camp, trailer and canoe," Lusk's wife, Megan, posted on Facebook. "There have been no signs of them. Please keep us in your prayers. We are praying and hoping both guys are found safe."

Idaho County Sheriff Doug Giddings said the search is focused on the river because a canoe was found upside down in the water and there's limited hiking areas due to the steep and rugged terrain.

"One of our deputies found tracks where two people got out of the river, hiked up to a hot springs, then came back down," Giddings said. "We're not aware of anyone else who was up there, so we're pretty sure those tracks are theirs. We believe that they stayed near the river."

Even with a mild winter, Giddings said, the river is swift this time of year.

"It was indicated to me that they didn't have life vests on," Giddings said. "But we're not positive because nobody saw them."

Friends and family members of the two missing men and outfitters joined law enforcement on Tuesday in the search. Some rode ATVs with search and rescue personnel in the mountains while others searched the river banks.

"Every outfitter and fisherman is aware of the case," Giddings said.

Giddings said divers are not part of the search because the river is so swift.

"Some people come here wanting to dive," he said. "We don't want to tell them no, but anyone with any sense is not going to dive. If we had a spot where we think they may be, then we could tie on and dive."

Giddings said there have been several drownings in the Salmon River in recent years.

"It's called the River of No Return," he said. "If you don't have a life vest and you fall in, chances are that you're not going to make it."

Idaho County Cpl. Jonny Wilson responded to the area of French Creek Salmon River Road on Sunday night and located the vehicle the men were reported to be driving. Wilson searched the immediate area by spotlight and was unable to locate them.

Then, on Monday, Cpl. Justin Scuka and Idaho Department of Fish and Game Officers Roy Kimmer and Dennis Brandt searched the river for several hours by boat, but still could not find the men.

Some friends maintained a positive outlook as Lusk, who works at Ground Force Worldwide in Post Falls, is an avid outdoorsman.

"Pat Lusk is one of the best men I know," Tom Hamilton posted on the Coeur d'Alene Press website. "He's also an expert woodsman and smart on his feet. I am praying for a safe return."
