Kevin Wayne Yokum, 27, a U.S. Navy information systems technician from Lake Charles, La., was stationed in the Pentagon.
His sister, Trudie Ceasar, said Yokum came from a military family and has a brother in the U.S. Army. He was a radio communications specialist.
"The Navy is what he always wanted," she said. The two spoke by phone every Sunday.
"Kevin was a fun-loving, silly guy," Ceasar said. "He was the life of every party."
