A week after 61-year-old Susan McLean was reported missing by her family from a Scottish vacation resort, the Cumberland County woman has not been found.

Search crews continued their efforts into the weekend, including searching the road out of Aberfeldy, Scotland, because, police said, investigators received information from the public suggesting potential sightings of McLean in the area the night she went missing.

On May 24, officers retraced McLean's steps and went door to door to speak with Aberfeldy residents for two hours in the hope of finding new information. Police have called the results "disappointing."

Police stopped motorists and pedestrians in the small town who may have a weekly routine, Temporary Chief Inspector Ian Scott told the Courier.

"Initially it doesn't appear that there's anything too positive come of that, which is obviously a little bit disappointing for us," Scott told the paper. "There was around 60 people spoken to but nothing of particular note has come off the back of it."

McLean, of Monroe Township, was on a two-week trip in Scotland with her husband, Donald, and two sons when she disappeared from the Moness Resort, which sits on the outskirts of Aberfeldy, Scotland.

She was last seen on Sunday at about 7:45 p.m. British Summer Time -- which is five hours ahead of the American Eastern Daylight Time -- walking along Crieff Road outside the grounds of the resort, which is a short walk into town. The resort area is a popular tourist spot that also attracts local walkers and cyclists. It sits about 70 miles north of Edinburgh.

McLean, a self-employed teacher of horseback riding and therapeutic riding, has been described as someone "not unfamiliar with the outdoors" in the days since her absence.

Scottish police have not provided any comment or speculation as to why McLean may have left the resort area, except to say that investigators believe she had left of her own volition.

Law enforcement have deployed a variety of resources over the course of the past week -- from police foot searches and search dogs to Mountain Rescue crews, the Dive and Marine Unit and a helicopter -- in the effort to comb the mountainous and rugged terrain. Scotland police have taken the investigation into the woman's disappearance seriously, but have said they have not found anything to suggest criminality.

"[Sunday's search effort] was warmly received by the local community, who have been very supportive of the police. From that side of things it's good work but it doesn't really help us with tracing Susan," Scott told the Courier. "Because of the amount of police activity and the media interest there's been I would have been quite surprised if somebody had come forward."

Donald McLean, a former Army veterinarian who works for the USDA in Harrisburg, released a statement to the public through Scottish police.

"Everyone in Aberfeldy has been very supportive and I want to thank all the people who have spoken to the police and given their time to help in our search for Susan," he said. "We just want her to be here with us, if anyone knows anything that might help to bring her back to our family, please let the police know so that we can bring her home."

Members of McLean's extended family flew to Scotland to support Donald and the couple's sons, but some of the family has since flown home.

Investigators have worked closely with the family, calling Susan's disappearance "out of character and unexplained."
