Greg Monks was reported missing after leaving the main strip in Albufeira in the Algarve region during the early hours of May 28.
The 38-year-old had arrived in the resort town the day before for a stag do.
The last official sighting of Greg was at around 3.27am on May 28 as he walked past a property in Cerro de Aguia.
According to Google Maps, this area is around an hour and 20 minutes walk from the main strip.
Police launched a major search to trace Greg, but on June 4, officers confirmed the body of a man, a 38-year-old British citizen, had been discovered on vacant land in Cerro de Aguia.
Greg’s mum, girlfriend, and cousin – who had flown out to join the search – will return to Scotland today (June 9) without him, with the repatriation process ‘set to take days’, the Daily Record reports.
Jillian Monks, Greg’s sister, stated that the family ‘will never truly know the full story’ but that they believe he ‘got lost’.

She said: “We don’t believe that anything untoward happened. Everything the police have told us adds up.
“We’ll never truly know the full story. But we believe he just got lost and ended up at the wrong place at the wrong time.
“It brings us some comfort knowing that Greg had all his belongings on him. He wasn’t robbed, he still had his phone and his wallet.
“He had all his cards and cash.”
We previously reported that a GoFundMe page was initially launched to support the search but had instead been updated to help the family bring Greg home and to plan his funeral.
It has so far raised £34,000.
Ms Monks highlighted that the family now ‘has some sense of closure’ as they plan to bring her beloved brother home this weekend.

She added: “The generosity and support have been incredible. We’re hoping to bring Greg home by the weekend. His mum, girlfriend, and cousin are going to fly home tonight.
“They wanted to fly back with him, but it has just not been possible. It has been the toughest time of our lives.
“We still can’t believe this has happened, but we’re glad we now have some sense of closure. I don’t know if any of us could have coped with even another day searching for my brother.
“I think it just shows in places like Albufeira, everyone needs to stick together and look after each other.
“His pals are absolutely devastated at what happened. Before everyone left the hotel that night, Greg made sure they all had a business card and a map from the hotel to help them find their way home.
“That’s the kind of person he was.”
Ms Monks further shared her family’s anger over how they discovered Greg had died.
She commented: “I knew Greg had been found before my mum and dad were told officially by police in Portugal.
“They were waiting in a police station to meet with officers when their phones went off with notifications to say Greg had been found.
“It is shocking that this was allowed to happen.”
