Jorge Mario Brenes Jaikel left his parents and one of his sisters in Vevey to go snowboarding alone last Wednesday at the Matterhorn Glacier Paradise in Zermatt.
He withdrew cash from an ATM, rented snowboarding equipment and made his way to the ski lift at around 10am, his sister, Mariela Brenes, told The Local in an email.
He has not been seen since.
His family became concerned when he did not return by train to Vevey as planned on Thursday. Their fears were exacerbated when he failed to show up for a work-related flight to London on Saturday.
“We haven’t found him so far but we’re still praying,” his cousin Fernando Acuna told The Local in a phone conversation on Monday afternoon.
“The police were out searching today and they will continue with dogs tomorrow.”
Jorge Mario Brenes Jaikel is an experienced snowboarder and is in good physical condition, but he had been having problems of late with his right ankle, his sister said.
He is 1.77 metres tall with brown eyes and black hair.
