A Hawaii-based Air Force staff sergeant has died at a military hospital several days after falling from a building in Thailand.

The Air Force said today that Staff Sgt. Danny Hollister was pronounced dead Tuesday at Tripler Army Medical Center.

The C-17 loadmaster assigned to the 535th Airlift Squadron suffered a head injury on March 9 after falling from a one-story building while deployed to Udon Thani, Thailand. He was in Thailand in support of Exercise Cope Tiger 2012.

The cause of the fall is under investigation.

Born in San Francisco and raised in American Samoa, Hollister was the son of a minister. The Rev. Tony Hollister says his son was about to become a father for the second time.

He was assigned to the 15th Wing at Joint Base Pearl Harbor-Hickam in Hawaii.
