TUCSON - The bell rang out at the downtown fire station Tuesday at 10:10 a.m.
That's the moment two years ago when the first shot was fired.
Mayor Jonathan Rothschild rang the bell 19 times in honor of the victims and survivors.
"We must never forget the good people who lost their lives or those whose lives were forever changed by the events of that day."
