Camille Kober, 52 and her boyfriend, Eric James Eide, 54, of Manton, haven't been seen or heard from since Dec. 21, when a Pacific Gas & Electric Co. employee reported seeing the couple walking onto PG&E property in Manton, Shasta County sheriff's Sgt. Troy Clegg said Wednesday.
Eide had gone to a nearby recycling facility a day earlier to turn in scrap metal and told employees that he would be returning to the PG&E property the next day to pick up more scrap metal, Clegg said.
It was not clear if the couple were authorized to remove any metal from the property, which is in a remote and rugged area about 40 miles southeast of Redding.
Eide's truck was found by PG&E workers Dec. 22, but there were no signs of him or Kober. Sheriff's officials had the truck towed Dec. 23.
On Christmas Eve, Eide's mother, reported the couple missing.
Search teams on the ground scoured the area for several days, and a California Highway Patrol helicopter crew searched from the air but found no signs of the couple, Clegg said.
"We looked in the water, on high spots, in low spots, and everywhere in between," Clegg said.
Investigators were also checking the couple's phone records and planned a search of a nearby creek later this week.
Kober and Eide had no history of disappearing, Clegg said.
