Former LA sheriff's deputy goes missing during hike on Greek island

A search and rescue operation is underway for a 59-year-old American who was reported missing Tuesday after failing to return from a hike on a Greek island.

Albert Calibet, a former Los Angeles Sheriff's Department deputy, failed to return from a hike on the Greek island Amorgos amid extreme heat, with temperatures above 100 degrees Fahrenheit. He was hiking from Aegiali toward Katapola, which takes roughly four hours.

Calibet reportedly began his hike at 7 a.m. local time on Tuesday and was last seen at 11 a.m. by walkers he met with on a trail, according to Hellenic Police.
