HONOLULU -- Family members confirmed that the sailor killed when the nuclear submarine USS San Francisco ran aground south of Guam was Joseph Ashley, 24, of suburban Akron.

Twenty-three other sailors suffered broken bones, bruises and cuts in the incident on Saturday.

Ashley, a second-class machinist, graduated in 1999 from Manchester High School where he played drums with the high school marching band.

His mother, Vicki Ashley, said he followed the footsteps of his father, Daniel Ashley, who served eight years in the Navy during the Vietnam War.

She said that just a few months ago, her son re-enlisted in the Navy for five more years. In June, he received his Dolphin pin, which qualified him as a submariner.

Friends and neighbors placed small American flags on the lawn of his family's home in Franklin Township, near Akron.

While the submarine suffered serious damage, the reactor itself is fine and the craft is heading back to Guam on the surface, escorted by a Coast Guard cutter and other ships.

A spokesman for the Pacific Fleet based at Pearl Harbor said the full extent of the damage won't be known until the 360-foot submarine with a crew of 137 reaches its home port Monday afternoon.

The spokesman said there's no information available on what the submarine struck. Located west of the International Date Line, Guam is a U.S. territory about 3,700 miles southwest of Hawaii.
