On today's 12th anniversary of the 9/11 attacks, Idaho Gov. Butch Otter and First Lady Lori Otter will lead a ceremony commemorating Idaho military members who died fighting terrorism since Sept. 11, 2001, starting at 10 a.m. at the Idaho Fallen Soldier Memorial, at 514 Jefferson St., in front of the former Capitol Annex now called the Idaho Law Learning Center. There, the names of the fallen soldiers are engraved as part of the memorial. The solemn commemoration will include presentations to the families of the four Idaho soldiers killed in the past year.
