 -- A sailor who was injured in a shooting at a military office in Chattanooga has died.

Randall Smith, a logistics specialist in the Navy, was among three people injured in the shooting at the Navy Operational Support Center Thursday. He died from his injuries early Saturday, said a U.S. official.

Smith is survived by his wife and three daughters, said a family spokesman.

Vice Admiral Robin Braun, Chief of the Navy Reserve, said in a statement: "The entire Navy Reserve Force is deeply saddened at the passing of LS2 Randall S. Smith. He was a dedicated Sailor who cared deeply about his family, his community, and his country. His service and, indeed, his life will remain an inspiration for his Shipmates and all who were fortunate enough to have known him."

Braun said his "heart goes out" to Smith's family.

"I hope they are able to find comfort in the knowledge that so many are keeping them in their thoughts and prayers and that LS2 Smith so faithfully and honorably served his country," Braun said. "Our thoughts are also with the entire Chattanooga community, and I want to thank the first responders and law enforcement community during this very difficult time."

Smith grew up in Paulding, Ohio, according to The Associated Press, and then joined the military after college.

Smith's grandmother, Linda Wallace, told the AP she didn't worry about her grandson getting hurt because he'd always been stationed in the U.S.

Wallace told the AP she last saw Smith over the Mother's Day weekend when he made a surprise visit to her home.

Four Marines were also killed in the Thursday shooting, along with the shooting suspect, Mohammod Youssuf Abdulazeez.

Investigators have said they not yet found a motive for the attack.
