Childress was a reservist staff sergeant on active duty at the local Air Force base, and one of two members of the armed services killed that night. He spent his days working on cyber systems and his nights competing on a bowling team with pals. He died throwing himself in front of a friend, Munirih Gravelly, who credits Childress with saving her life. "I feel really sorry ... that he's gone," she told L.A.'s NBC4. "That none of us were able to at least hold his hand and look him in the eye while he passed."
