Greg Monks, a 38-year-old British tourist from Glasgow, has been missing for four days after a night out in Albufeira, Portugal, where he was attending a stag do. His family, including his parents and girlfriend Nicole Ashleigh Kelso, have traveled to the area to assist in the search, as his disappearance is considered out of character. Despite police locating him near Cerro da Aguia during the time he went missing, there have been no sightings or updates, prompting his sister Jillian to appeal for help from the local community to check any surveillance footage from that night.
