It has now been 15 years since the deadly shooting that changed our state and our country forever. Back on Jan. 8, 2011, a gunman opened fire at an event hosted by former Arizona Congresswoman Gabby Giffords in Tucson. Six people were killed and 13 others were injured, including Giffords. #abc15 #inmemoriam #tucsonshooting #arizona #news #gabbygiffords
