Rigel said he could not identify the student but believes the man was from outside Mississippi.

James Horak Jr., 56, an instructor for the Emerald Coast Skydiving Center in Elberta, Ala., died Saturday in a swamp about a mile from the airport in Lumberton, Miss. He was safety-conscious and had made more than 8,000 dives, said his wife, Debbie Horak.

LUMBERTON, Miss. — A skydiving instructor from Pensacola, Fla., died in a swamp after a tandem jump that left his student hospitalized, Lamar County Sheriff Danny Rigel said Sunday.

Three other skydivers who jumped with them told investigators that equipment appeared to malfunction, Rigel said Sunday.


''They said something appeared to be not right. There appeared to be some entanglement with the lines, but I'm not qualified to say what that was or even speculate about it,'' he said.

Federal Aviation Administration inspectors will look at whether the parachutes were properly rigged by a qualified rigger and whether the parachute operation met FAA regulations, but local authorities will investigate the accident and determine probable cause, FAA spokeswoman Kathleen Bergen said Sunday.

The sheriff's office was called at 1:40 p.m. Saturday, more than 3 hours after the jump, Rigel said. He said he did not know the reason for the delay.

The owner of a hunting lease for the area found the men, and the student was taken to Forrest General Hospital. A nursing supervisor there said the family had not authorized release of any information about him.

An autopsy is planned for Horak, probably Monday, Rigel said.

Debbie Horak said she and their three children were waiting for autopsy results to find out what happened to her husband, a full-time physician's assistant and part-time pilot and skydiving instructor.

''My husband is a very, very skilled skydiver. Very safety-conscious,'' she said. She said he had no medical conditions and described him as healthy.
