The suitcase and cell phone of the Pennsylvania man who was found dead in an elevator shaft at Tampa International Airport early Friday have been located, authorities said.

Investigators are treating the death of Chad Wolfe, 31, of West Newton, Pa., as an unexplained death. Airport spokesperson Janet Zink said Wolfe's suitcase and cell phone were located on the seventh floor of the short-term parking garage, which is information that was not previously released.

Wolf arrived in Tampa from Atlanta on Delta flight 2233 around 12:15 a.m. He entered an elevator shaft on the third floor when the elevator was stopped on the seventh floor, officials said.

A nearby elevator stopped working around 3 a.m, and when maintenance workers were working on it, they discovered Wolfe's body around 10:45 a.m.

Investigators have found no signs of foul play, officials said. The medical examiner will determine a cause of death, and airport officials are investigating how Wolfe got into the elevator shaft.
