It has been three days since Albert Calibet, an American tourist, disappeared on an island in Greece. Family and friends are more eager than ever to find him.

Calibet was reported missing on Tuesday, June 11, after he did not return from a hike on the island of Amorgos that he embarked on earlier that day.

The missing man is a retired member of the Los Angeles Sheriff’s Department, according to CW affiliate KTLA, which spoke with some of his friends and family.

“The clock is ticking, and we feel like we’re losing time,” said family friend Robin Wynston Lynn.

Sandrine Cutright, Calibet’s sister-in-law, said her in-law is “physically fit” and “swims every day.” Loved ones claim he is an experienced hiker, as well.

But Lynn said the island has “few resources,” especially on that part where Calibet is believed to have gone missing.

Cutright also said rescue teams must pause their search each night due to the terrain.

Calibet joined the LASD in April 1998 and formally retired two decades later, in 2018, according to CBS affiliate KCBS-TV. However, the department said he still worked part-time shifts to help with staffing shortages.

In a statement, L.A. County Sheriff Robert Luna said the department is “actively collaborating with multiple agencies abroad to provide assistance in the search” for Calibet, according to KTLA and KCBS-TV.

“Our thoughts and prayers are with Deputy Calibet's family and friends and our hope is that we can bring him home safely,” Luna added.

Lynn also begged for help. “Anyone who hears this story and has resources, please come help us save our friend Albert,” she said. “Send the cavalry for Albert Calibet.”

Calibet is said to be familiar with the area where he went missing. Amorgos’ deputy mayor of tourism, Popi Despotidi, told CNN that Calibet has been traveling to the island "almost every year” for the last decade.

“It is strange because he is not a person who walked the route for the first time,” Despotidi told international news organization Greek Reporter. “He knows Amorgos better than me.”
