Kaua'i County officials and family members are asking for help in finding an Orem, Utah, man who went missing while on a hike with his family last week in the Wailua Falls area.

Ryan Soper and his family were with a tour guide on a hike last Thursday. At one point Soper fell from a tree and landed on his in-laws, breaking his mother-in-law's ankle, the Salt Lake Tribune reported.

Soper's head and shoulders landed against a rock. While the group attended the his mother-in-law, Soper walked off and has not been seen since.

Amie Soper told the Tribune that her husband may have suffered a concussion in the fall but disregarded it because he had had a headache before the hike.

The newspaper said Kaua'i officials have suspended the search.

Soper, 26, is described as 5 feet 10 and about 240 pounds. He has short blond hair, blue eyes and a fair complexion.

He was wearing a black Under Armor shirt with long sleeves and a pair of black and white board shorts.

Anyone with information about Soper is asked to called Kaua'i police dispatch at 241-1711.
