The sisters of Greg Monks, a 38-year-old plant mechanic from Glasgow, have made a fresh plea for information as the search for their missing brother enters its second week.
Greg vanished just hours into a five-day stag do in Albufeira, Portugal.
He was last seen in the early hours of May 28, the first night of the trip with friends.
Greg had told his pals he was heading back to his holiday apartment but has not been seen since.
Since his disappearance, his family has travelled to Portugal to search for clues about his whereabouts.
His sisters, Jillian and Carlyn Monks, are urging anyone with information to come forward and help the Portuguese police with the investigation.
Carlyn expressed the family’s worry to Sky News, saying, “As a family we’re worried sick. It’s so unlike him, but myself and Jillian are just trying to hold each other up back home.”
Jillian added, “He deserves to be home. We need him home. He needs to be back with his family, and it’s unimaginable if he’s just lying somewhere that we can’t find him.”
She described Greg as quiet, hardworking, happy in his relationship, a great uncle, and a devoted family man.
Police have told the family that Greg was last spotted on CCTV walking alone in the quieter residential area of Cerro de Águia.
This location is around four miles from the Novochoro Apartments where he was staying.
The area is rural, with many trees and rough terrain, and is over an hour’s walk west of the busy Albufeira Strip where Greg is believed to have parted ways with his friends.
Jillian said, “He’s been spotted twice walking alone there on CCTV, the area’s residential, it’s rural – there’s really a lot of trees and rocks, it’s got quite rough terrain.”
The sisters have asked local residents to check any home security footage and contact police if they have any information.
“If you see his picture, and you know anything, get in touch. If you live in the area, or the surrounding area, and you have home security please check it and get in touch,” Jillian urged.
She also expressed gratitude for the support they have received online and from people in Portugal who are volunteering to search the area despite the risks.
“We’re getting lots of support online, especially even people over there who are using the last days of their holidays to go up to this area and look for them. People are risking themselves to look in areas they shouldn’t have to look,” she said.
The sisters are trying to determine whether Greg took a taxi to the residential area or walked there, as this would influence where the search should focus.
“We want to know if he got a taxi there, if he used his card. He only had his card with him. We want to know if he got a taxi there or are we wasting time searching this area,” Jillian said.
The family understands the investigation will soon be passed to the national police, but they feel time is critical.
“We won’t have a meeting with them or an update for a day or two, and time is not what we have,” Jillian added.
There is concern Greg may have become lost or suffered an accident in the unfamiliar, rough terrain.
Hospitals have been checked but with no success so far.
Police have yet to carry out a full search of medical centres, which would include checking wards for unidentified patients.
Greg’s sisters describe him as a “really hard worker” and “quiet guy,” making his disappearance particularly alarming.
Greg has a distinctive Thor-type Viking tattoo on the top of his right arm, visible if he is wearing a vest or no shirt.
He is believed to have been wearing a navy blue Nike shorts and top set when he went missing.
To help with the search, a GoFundMe appeal has raised over £21,550 as of Wednesday morning.
Carlyn has also made a heartfelt online plea, asking people to continue sharing their brother’s story.
She wrote, “Please keep sharing and help get my brother home.”
