Search and rescue crews suspended their search Friday for a missing woman who walked away from her residence four days earlier, leaving her dogs, car and possessions behind.

Leslie Jay Main, 48, was last seen Monday near her campground rental unit at 34161 Ophir Road. She is described as 5 feet, 6 inches tall and weighing about 115 pounds.

"We've searched the area several times over and we just haven't located her," Curry County Undersheriff Bob Rector said late Friday.

The area being searched is swampy and heavily vegetated, Rector said.

"We will bring in an air scent dog on Sunday or Monday, when the weather is suppose to be better," he said.

"At this point we are classifying this as an open missings person case," he said.

Authorities believe Main left her residence late Monday evening.

At 9:51 a.m. Tuesday, the Sheriff's Department received a call from Janet Saks, manager of Honeybear Campground, off Highway 101 in Ophir, who was concerned about a tenant staying at the campground, Rector said.

Saks said Main's dogs were found running loose a mile or so from the campground.

"A neighbor found the dogs and called us, wanting to know if anybody at the campground had lost some dogs," Saks said Thursday.

Saks recognize the dogs and went to check on Main and found her unit door standing wide open.

"We don't know where she went; she could have run after the dogs at night and fell down, or went to the beach. We just don't know," Saks said.

Main recently had a kidney transplant and had been traveling to Coos Bay several times a week for dialysis treatment, Saks said.

"She was frail and it's possible she fell down somewhere," Saks said.

On Tuesday, Sheriff's Deputy Joel Hensley did an initial search of the area. Main's car was found at the unit as were items inside that Hensley believe she would likely have taken with her if leaving for an extended period of time.

Sheriff's Lt. John Ward responded to assist and a hasty search of the immediate area was completed without success. Search and Rescue (SAR) members were called out and began an intensive search.

The Sheriff's Office is asking that anyone with knowledge of Main's whereabouts to call 541-247-3242.
