The city is adding biographies and "quick response codes" to hero square memorials so residents can quickly find out more about the military men and women for whom those corners are named. On Monday, family members of Lance Cpl. Alex Arredondo, a Marine killed in action during the Iraq War in 2004, joined dignitaries for a re-dedication of the corner of St. Rose and South streets. That corner has honored the JP-bred soldier for a decade. On Monday, officials unveiled a more extensive plaque that tells more of Alex Arredondo's story.
