Authorities say an investigation is under way into the deaths of a skydiving instructor and a student, both from Iceland, who died during weekend jumps with a group in Florida.

Pascoe County sheriff’s spokeswoman Melanie Snow said the two men took part with 20 other people Saturday in jumps in Zephyrhills, about 30 miles northeast of Tampa. Authorities say a search began when only 20 of the 22 skydivers returned.

Snow said the bodies were found near each other Saturday evening in woods south of the Zephyrhills Municipal Airport. She would not comment whether their parachutes of the skydivers had opened, saying that was part of the investigation.

The spokeswoman later said the dead were identified as 41-year-old instructor Orvar Arnarson and 25-year-old student Andrimar Pordarson. No hometowns were given.
